Chymotrypsin is a member of the trypsin family of serine proteases and is one of the first proteins successfully studied by X-ray crystallography. It is secreted into the intestine as the inactive precursor chymotrypsinogen; four sequential cleavages of the peptide bonds following residues 13, 15, 146 and 148 occur to generate the active pi, delta, kappa and alpha forms of chymotrypsin. (13)C NMR has shown [O'Connell & Malthouse (1995). Biochem. J. 307, 353-359] that when the delta form of… 

Substrate binding and specificity of rhomboid intramembrane protease revealed by substrate–peptide complex structures

It is proposed that the homologous region of members of the wider rhomboid‐like protein superfamily may have similar substrate or client‐protein binding function and is generated a model of the Michaelis complex of the substrate bound in the active site of GlpG.

Intrinsic evolutionary constraints on protease structure, enzyme acylation, and the identity of the catalytic triad

This analysis revealed the orientation of the base determines the stereochemistry of catalysis and elucidated why threonine does not substitute for serine in the catalytic triad, and proposed a molecular basis for the increased enzymatic efficiency introduced by the γ-methyl of Thr.

Molecular mechanism of prothrombin activation by Von Willebrand factor-binding protein

VWbp binds weakly to ProT to form an inactive complex, which is activated through a slow conformational change by tripeptide chromogenic substrates and its specific physiological substrate, identified here as fibrinogen (Fbg).

Thrombin-Like Enzymes in Snake Venoms

Snake venoms, particularly from vipers, are rich sources of serine proteinases, some of which contain thrombin-like activity, but as a result of gene duplication, accelerated point mutations and ASSET, venom TLEs have evolved a diversity of activities.

Alkylating HIV-1 Nef - a potential way of HIV intervention

The data suggest that this Cys55-specific alkylation mechanism may be exploited to develop a new class of anti HIV drugs.
