title: Chondroitin O-methyl ester: an unusual substrate for chondroitin AC lyase.
abstract: Chondroitin O-methyl ester was depolymerized by chondroitin AC lyase (EC 4.2.2.5) from Flavobacterium heparinum. The major product isolated from the depolymerization reaction was found to be methyl alpha-L-threo-hex-4-enopyranosyluronate-(1-->4)-2-acetamido-2-deoxy-alpha,beta-D-galactopyranoside.
