The canonical methionine 392 of matrix metalloproteinase 2 (gelatinase A) is not required for catalytic efficiency or structural integrity: probing the role of the methionine-turn in the metzincin metalloprotease superfamily.

Abstract excerpt

Matrix metalloproteinases (MMPs) are an important family of extracellular proteases that process a variety of biologically significant molecules. MMPs are members of the metzincin superfamily of >770 zinc endopeptidases, which includes astacins, serralysins, adamalysins, leishmanolysins, and snapalysins. Metzincins are characterized by an absolutely conserved methionine residue COOH-terminal to the third...
