title: Vitamin K-dependent carboxylation of poly-L-glutamate.
abstract: Poly-L-glutamate preparations of varying chain length were used as substrates for bovine liver vitamin K-dependent carboxylase. The quality of these substrates (as measured by their apparent kinetic constants) was comparable to that of the more commonly used tri- and pentapeptides, but the maximal reaction rate increased at increasing chain length.
