Neosartorya fischeri (strain ATCC 1020 / DSM 3700 / CBS 544.65 / FGSC A1164 / JCM 1740 / NRRL 181 / WB 181) (Aspergillus fischerianus)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Protostadienol synthase which cyclizes (3S)-oxidosqualene to (17Z)-protosta-17(20),24-dien-3-beta-ol (protostadienol), the biosynthetic precursor of helvolic acid, a secundary metabolite which promotes virulence.By similarity

Catalytic activityi

(3S)-2,3-epoxy-2,3-dihydrosqualene = (17Z)-protosta-17(20),24-dien-3-beta-ol.

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.
