LITERATURE
in presence and absence of beta-(1->4)-mannobiose, and comparison with 4-O-beta-D-mannosyl-D-glucose phosphorylase MP1. The structures of the two enzymes differ at the +1 subsite of the substrate-binding pocket. Three loops are proposed to determine the different substrate specificities. Loop2 restricts the derivatives at the C6 position of the +1 substrate residue in beta-(1,4)-mannooligosaccharide phosphorylase MP2
