protein biochemistry
in protein biochemistry, biochemists specially study proteins as complex polymers. protein biochemistry is the study of the chemical structure of proteins, including individual amino acids, their linkage as well as physical structure of proteins. proteins, especially globular proteins, are three dimensional in nature. proper function of globular proteins is tightly related to their three-dimens...
متن کاملBiochemistry of protein prenylation.
Covalent modification by isoprenoid lipids (prenylation) is now recognized as a mechanism to promote membrane interactions and biological activities of a variety of cellular proteins. Both the 15-carbon farnesyl and 20-carbon geranylgeranyl isoprenoids are involved in these modifications, which occur on carboxyl-terminal cysteine residues of proteins (Fig. 1). Known prenylated proteins include ...

ANTICOAGULANT PATHWAY P ROTEIN-C is a vitamin-K-dependent plasma zymogen.’ After activation, activated protein-C differs from the vitamin-K-dependent plasma clotting factors in that it potently inhibits coagulation5 by inactivating factors V6’7 and VIII,7’8 and it facilitates fibrinolysis in vivo9”#{176} by elevating circulating plasminogen activator levels.tO Clinical evidence of protein-C inv...
متن کاملBiochemistry of the chromogranin A protein family.
The secretory granules of adrenal medullary chromaffin cells synthesize, store and then liberate catecholamines by exocytosis after cell stimulation with acetylcholine, itself liberated from the splanchnic nerve (for review, see Viveros, 1975). Apart from adrenaline and noradrenaline, chromaffin granules contain a great number of molecules, essentially proteins, which are co-secreted with the c...
متن کاملPROTEIN BIOCHEMISTRY Protein Interaction Methods - Toward an Endgame
T housands of new protein-protein interactions have been identified through the use of the two-hybrid system, shedding much light on molecular and celh lar biology. In the next decade, we can hope to see large catalogs of protein interactions predictive models of those .inteJ'acliolls, aud at lea tome ability to follow networks of those i.nteractions in real time. Here, we review newer methods ...
