Title
A 3,6-anhydro-D-galactosidase produced by Zobellia galactanivorans. This is an exo-lytic enzyme that hydrolyzes terminal 3,6-anhydro-D-galactose from the non-reducing end of carrageenan oligosaccharides.
Evidence: X-ray crystallographic evidence shows the active site amino acids are shared between the dimer interface. PDBePISA shows an interface area of 3521 Anstroms2.
