Beta-porphyranase (EC 3.2.1.178, porphyranase, PorA, PorB, endo-beta-porphyranase) is an enzyme with systematic name porphyran beta-D-galactopyranose-(1->4)-alpha-L-galactopyranose-6-sulfate 4-glycanohydrolase. This enzyme catalyses the following chemical reaction: Hydrolysis of beta-D-galactopyranose-(1->4)-alpha-L-galactopyranose-6-sulfate link ages in porphyran. The backbone of porphyran consists largely (~70%) of (1->3)-link ed beta-D-galactopyranose followed by (1->4)-link ed alpha-L-galactopyranose-6-sulfate.
