Gene

yihS

Protein

Sulfoquinovose isomerase

Organism

Escherichia coli (strain K12)

Length

413 amino acids

Function

Catalyzes the isomerization of sulfoquinovose (SQ) to 6-deoxy-6-sulfo-D-fructose (SF). In vitro, can also catalyze the interconversion of mannose, fructose and glucose, or lyxose and xylulose, but has extremely low activity with glucose.

Similarity

Belongs to the N-acylglucosamine 2-epimerase family.

Mass
