Function

MANA_HYPJR 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).[1] [2] [3] [PROSITE-ProRule:PRU00597][SAM:MobiDB-lite][4]
