additional information | enzyme exhibits a non-random mode of action when acting on mannuronan and alginates of various monomeric compositions. On average 10 residues are epimerised for each enzyme-substrate encounter. A hexameric oligomer is the minimum size to accommodate activity. For hexa-, hepta- and octameric substrates the third M residue from the nonreducing end is epimerised first | Azotobacter vinelandii | ? | - |
