Protein

Isopenicillin N synthase

Gene

pcbC

Organism
Lysobacter lactamgenus
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Removes, in the presence of oxygen, 4 hydrogen atoms from delta-L-(alpha-aminoadipyl)-L-cysteinyl-D-valine (ACV) to form the azetidinone and thiazolidine rings of isopenicillin.

Catalytic activityi

N-((5S)-5-amino-5-carboxypentanoyl)-L-cysteinyl-D-valine + O2 = isopenicillin N + 2 H2O.

Cofactori

Protein has several cofactor binding sites:

Pathwayi: penicillin G biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes penicillin G from L-alpha-aminoadipate and L-cysteine and L-valine.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Isopenicillin N synthase (pcbC)
  3. no protein annotated in this organism
This subpathway is part of the pathway penicillin G biosynthesis, which is itself part of Antibiotic biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes penicillin G from L-alpha-aminoadipate and L-cysteine and L-valine, the pathway penicillin G biosynthesis and in Antibiotic biosynthesis.

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.
