Protein

3-hydroxy-3-methylglutaryl-coenzyme A reductase

Gene

hmg1

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

Functioni

Catalyzes the conversion of HMG-CoA to mevalonate. It is the rate-limiting enzyme of the sterol biosynthesis pathway. Involved in ergosterol biosynthesis.2 Publications

Catalytic activityi

(R)-mevalonate + CoA + 2 NADP+ = (S)-3-hydroxy-3-methylglutaryl-CoA + 2 NADPH.

Pathwayi: (R)-mevalonate biosynthesis

This protein is involved in step 3 of the subpathway that synthesizes (R)-mevalonate from acetyl-CoA.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Acetyl-CoA acetyltransferase (erg10)
  2. Hydroxymethylglutaryl-CoA synthase (hcs1)
  3. 3-hydroxy-3-methylglutaryl-coenzyme A reductase (hmg1)
This subpathway is part of the pathway (R)-mevalonate biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (R)-mevalonate from acetyl-CoA, the pathway (R)-mevalonate biosynthesis and in Metabolic intermediate biosynthesis.

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.
