Initiation-specific alpha-1,6-mannosyltransferase

Gene

och1

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Mannosyltransferase involved in outer chain elongation of asparagine-linked oligosaccharides of the type Man9GlcNAc2. May otherwise add the first alpha-1,6-mannose to the Man8GlNAc2 core oligosaccharide from the ER. Represents the first enzymatic event required for synthesis of outer chain mannose linkages on yeast secretory proteins.2 Publications

Catalytic activityi

Transfers an alpha-D-mannosyl residue from GDP-mannose into lipid-linked oligosaccharide, forming an alpha-(1->6)-D-mannosyl-D-mannose linkage.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
