RT "A novel endo-beta-mannanase gene in tomato LeMAN5 is associated with
RT anther and pollen development.";
RL Plant Physiol. 134:1080-1087(2004).
CC -!- FUNCTION: May be involved in weakening of anther wall during pollen
CC development.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Random hydrolysis of (1->4)-beta-D-mannosidic linkages in
CC mannans, galactomannans and glucomannans.; EC=3.2.1.78;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC -!- DEVELOPMENTAL STAGE: Expressed in anthers and pollen of unopened bud
CC and opening flowers, but not in fully opened flowers.
CC {ECO:0000269|PubMed:14976239}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 5 (cellulase A) family.
CC {ECO:0000305}.
