FAMILY

glycosyl hydrolase 5 (cellulase A) family

DESCRIPTION

Also known as MANA_HYPJR, man1. Endo-1, 4-mannanase that catalyzes the random hydrolysis of (1->4)-beta-D-mannosidic linkages in mannans and heteromannans. It is a crucial enzyme for depolymerization of seed galactomannans and wood galactoglucomannans. Active against locust bean gum and ivory nut mannan, releasing mainly tri- and disaccharides (PubMed:7793911, Ref.3, Ref.4, PubMed:8529653). Also has transglycosylation activity. Transglycosylation of two mannotrioses into a mannohexaose is the major transglycosylation route (PubMed:8529653, Ref.7, PubMed:24950755). Monomer.
