Other name(s): | glucosylmannosidase; endo-α-D-mannosidase; endo-α-mannosidase; endomannosidase; glucosyl mannosidase; MANEA (gene name); glycoprotein glucosylmannohydrolase | ||||||||||||||
Systematic name: | glycoprotein glucosylmannohydrolase (configuration-retaining) | ||||||||||||||
Comments: | The enzyme catalyses the hydrolysis of the terminal α-D-glucosyl-(1→3)-D-mannosyl unit from the GlcMan9(GlcNAc)2 oligosaccharide component of N-glucosylated proteins during their processing in the Golgi apparatus. The name for the isomer is based on a nomenclature proposed by Prien et al [7]. | ||||||||||||||
