Protein

Bifunctional protein PutA

Gene

putA

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Oxidizes proline to glutamate for use as a carbon and nitrogen source and also function as a transcriptional repressor of the put operon.

Catalytic activityi

L-proline + a quinone = (S)-1-pyrroline-5-carboxylate + a quinol.
L-glutamate 5-semialdehyde + NAD+ + H2O = L-glutamate + NADH.

Cofactori

Pathwayi: L-proline degradation into L-glutamate

This protein is involved in step 1 and 2 of the subpathway that synthesizes L-glutamate from L-proline.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Bifunctional protein PutA (putA)
  2. Bifunctional protein PutA (putA)
This subpathway is part of the pathway L-proline degradation into L-glutamate, which is itself part of Amino-acid degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-glutamate from L-proline, the pathway L-proline degradation into L-glutamate and in Amino-acid degradation.

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.
