Interactioni

Subunit structurei

yscS is synthesized as one polypeptide chain precursor which after carbohydrate modification in the secretory pathway yields two active precursor molecules. The proteolytically unprocessed forms are associated with the membrane, whereas the mature forms of the enzyme are soluble.

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.
