orsE

Gene
orsE
Protein
Dehydrogenase orsE
Organism
Emericella nidulans (strain FGSC A4 / ATCC 38163 / CBS 112.46 / NRRL 194 / M139)
Length
348 amino acids
Function
Dehydrogenase; part of the gene cluster that mediates the biosynthesis of orsellinic acid, as well as of the cathepsin K inhibitors F9775 A and F9775 B (PubMed:19666480, PubMed:20174687). The non-reducing polyketide synthase orsA produces orsellinic acid by condensing acetyl-CoA with 3 malonyl-CoA units (PubMed:19666480, PubMed:20174687). Further modifications by the decarboxylase orsB and the tyrosinase-like protein orsC lead to the production of F9775 A and F9775 B (PubMed:20174687). The functions of orsD and orsE remain unclear since only orsB and orsC are required to convert orsellinic acid into F9775 A and F9775 B (PubMed:20174687).
Similarity
Belongs to the zinc-containing alcohol dehydrogenase family.
