Reaction: MAN1B1 hydrolyses 1,2-linked mannose (a branch)

- in pathway: ER Quality Control Compartment (ERQC)
The enzyme ER Man I can slowly trim up to four of the mannoses on the N-glycan on unfolded proteins accumulated in the ER. This step describes the removal of the mannose in the A position (Hirao et al, 2006; Frenkel et al, 2003).
