Getting creative @ SHOP

I thought of getting creative and made some new entries for THE SHOP!

5uv0: Creativity in the SHOP

In moments of boredom or concern, seeing how beautiful the structures of nature are can reassure and inspire! I went back to my favourite molecules and selected some protein structures to bring some dynamism and creativity in our SHOP. Have a look at the NEW items with this protein!

This crystal structure belongs to the (+)-Limonene Synthase from Citrus sinensis … that is behind the aroma of orange and limoncello!

Crystal Structure of (+)-Limonene Synthase from Citrus sinensis

This enzyme produces the aromatic molecule limonene. imonene takes its name from French limon (“lemon“). Limonene is a chiral molecule, and biological sources produce one enantiomer: the principal industrial source, citrus fruit, contains D-limonene ((+)-limonene), which is the (R)enantiomer.  D-Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation..

This crystal structure belongs to the Tomato spotted wilt tospovirus nucleocapsid protein-ssDNA complex … one of the natural enemies of tomatoes but in purple!

Tomato spotted wilt tospovirus nucleocapsid protein-ssDNA complex

Tomato spotted wilt virus is a spherical negative-sense RNA virus that has a diameter around 100 nm.  It is one of the most economically devastating plant viruses in the world. Transmission can only occur when larvae stage thrips acquire the virus. The larvae stage for thrips lasts around 1-3 days. The virus is acquired by thrips when they feed on infected plants.  (read more DOI: 10.1128/JVI.01002-17 and Wikipedia)

This crystal structure belongs to the POTATO CARBOXYPEPTIDASE … one of the nemesis of proteins, argh!!

REFINED CRYSTAL STRUCTURE OF THE POTATO INHIBITOR COMPLEX OF CARBOXYPEPTIDASE A AT 2.5 ANGSTROMS RESOLUTION

A carboxypeptidase is a protease enzyme that hydrolyzes (cleaves) a peptide bond at the carboxy-terminal (C-terminal) end of a protein or peptide. This is in contrast to an aminopeptidases, which cleave peptide bonds at the N-terminus of proteins. Humans, animals, bacteria and plants contain several types of carboxypeptidases that have diverse functions ranging from catabolism to protein maturation.(read more DOI: 10.1038/nature06956 and Wikipedia)

This crystal structure belongs to the Neuraminidase such a surprising vegetable.

N1 Neuraminidase H274Y + oseltamivir

Neuraminidase is a key protein of influenza viruses and in this structure one inhibitor is also present bound to it. The best-known neuraminidase is the viral neuraminidase, a drug target for the prevention of the spread of influenza infection. The viral neuraminidases are frequently used as antigenic determinants found on the surface of the influenza virus. Some variants of the influenza neuraminidase confer more virulence to the virus than others. The study of neuraminidases and how they evolve, and the research of novel inhibitors are key for having antiviral drugs in the future (read more DOI: 10.1038/nature06956 and Wikipedia)

This crystal structure belongs to the IgNAR antibody domain C3… a protein from shark! what else can I say?

IgNAR antibody domain C3

Sharks have smaller antibodies than usual. IgNAR shows significant structural differences to other antibodies. It has five constant domains (CH) per chain instead of the usual three, several disulfide bonds in unusual positions, and the complementarity-determining region 3 (CDR3) forms an extended loop covering the site which binds to a light chain in other antibodies. These differences, in combination with the phylogenetic age of the cartilaginous fishes, have led to the hypothesis that IgNAR could be more closely related to a primordial antigen-binding protein than the mammalian immunoglobulins. Non-vertebrates do not have antibodies at all. (read more DOI: 10.1073/pnas.1321502111 and Wikipedia)

This crystal structure belongs to the potato multicystatin … such a surprising vegetable.

Potato Multicystatin

Potato (Solanum tuberosum) multicystatin an inhibitor of protease of the family Cys protease and found in the subphellogen layer of potato tubers. In contrast with cystatins from other plant and animal sources, this protein has a high molecular mass of 85 kDa/monomer, compared to 8 or 25 kDa. It can also bind and inhibit several Cys proteases (e.g., papain) simultaneously, and the term multicystatin thus refers to its multiple inhibitory domains (read more DOI: 10.1105/tpc.108.064717 and doi: 10.1105/tpc.108.064717)

This crystal structure belongs to the THE SWEET PROTEIN THAUMATIN that is a protein much sweeter than common sugar but giving very little calories! Is the sweetener of the future coming from biotech?

This crystal structure belongs to the THE SWEET PROTEIN THAUMATIN
Thaumatin, the sweet protein.

Proteins can be sweet and thaumatin is one of the best int his respect. The thaumatins were first found as a mixture of proteins isolated from the katemfe fruit (Thaumatococcus daniellii Bennett) (marantaceae) of west Africa. Some proteins in the thaumatin family of sweeteners are roughly 2000 times more potent than sugar. Although very sweet, thaumatin’s taste is markedly different from sugar’s. The sweetness of thaumatin builds very slowly. Perception lasts a long time, leaving a liquorice-like aftertaste at high usage levels. Thaumatin is highly water-soluble, stable to heating, and stable under acidic conditions. (read more DOI: 10.1107/S0907444994005512 or Wikipedia)

This crystal structure belongs to the Crystal Structure of the Lumenal Domain of Calnexin that is a protein with a very long appendage… like a ball on the leash!

Crystal Structure of the Lumenal Domain of Calnexin

It consists of a large (50 kDa) N-terminal calcium-binding lumenal domain, a single transmembrane helix and a short (90 residues), acidic cytoplasmic tail. Calnexin is a chaperone, meaning that its job is to assist protein to reach their correct folding and ensure quality control. It specifically acts to retain unfolded or unassembled N-linked glycoproteins in the endoplasmic reticulum (read more at Wikipedia and DOI: 10.1016/s1097-2765(01)00318-5)

This crystal structure belongs to the SOLUTION STRUCTURE OF CA2+-BOUND STATE OF CANINE MILK LYSOZYME that is clearly a compact ball-like protein.

SOLUTION STRUCTURE OF CA2+-BOUND STATE OF CANINE MILK LYSOZYME

Lysozyme is a small protein that attacks bacteria and breaks down one of their crucial structures, the membrane that holds them together. In particular, it cleaves the β-1,4-glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine of peptidoglycan. Made of sugars and crosslinked peptides, peptidoglycan gives structure and confers structural integrity to to know more. It degrades (hydrolysespeptidoglycan, the building block of bacterial cell-wall. Being able to attack one of the components present in all bacteria, it is a powerful weapon not only in medicine but also for biotech applications. (read more at Medium)

CANINE AND BOVINE GRANULOCYTE-COLONY STIMULATING FACTOR (G-CSF)

This protein is a member of the cytokine family and carries sugar modiciation (they are glycoproteins) that stimulate the differentiation and proliferation of blood cells. They are small proteins with a molecular mass of about 19 kDa and an amino acid sequence identity of about 80%.The structure is formed by alpha-helices that form an antiparallel 4-alpha-helical bundle with up-up-down-down connectivity. The human and canine proteins are really somilar in structure to each other. (ref.DOI: 10.1006/jmbi.1993.1617)
