ERManI Products

ERManI (MAN1B1) catalyzes the first mannose-trimming step in maturation of Asn-linked oligosaccharides. It trims a single alpha-1,2-linked mannose residue from Man(9)GlcNAc(2), specifically converting it to Man8GlcNAc isomer B. ERManI may be involved in glycoprotein quality control since it is important to target misfolded glycoproteins for degradation.
