Function
Displays some glucuronoyl esterase activity in vitro, since it is able to hydrolyze methyl 4-O-methyl-D-glucopyranosyluronate, allyl D-glucuronate, benzyl D-glucuronate and D-glucuronic acid methyl ester. However, esters of glucuronic acid are probably not its biological substrate, as they are not present in the marine environment. Can also hydrolyze a range of other esters, including p-nitrophenyl acetate. More likely biologically-relevant substrates for MZ0003 and other marine bacterial CE15s are algal cell wall polysaccharides, as these would be readily available in this environment and could be used as energy sources.
