Protein BMEI1586

Gene

BMEI1586

Organism
Brucella melitensis biotype 1 (strain 16M / ATCC 23456 / NCTC 10094)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

In vitro, catalyzes the epimerization of trans-4-hydroxy-L-proline (t4LHyp) to cis-4-hydroxy-D-proline (c4DHyp) and that of trans-3-hydroxy-L-proline (t3LHyp) to cis-3-hydroxy-D-proline (c3DHyp), albeit with very low efficiency. The physiological substrate may be different (PubMed:24980702). Displays neither proline racemase activity nor t3LHyp dehydratase activity (PubMed:17849014, PubMed:24980702).1 Publication2 Publications

Catalytic activityi

Trans-4-hydroxy-L-proline = cis-4-hydroxy-D-proline.1 Publication

Kineticsi

kcat is 0.082 sec(-1) for t4LHyp epimerization. kcat is 0.085 sec(-1) for t3LHyp epimerization.1 Publication

Manual assertion based on experiment ini

  1. KM=4.5 mM for trans-4-hydroxy-L-proline1 Publication
  2. KM=2.6 mM for trans-3-hydroxy-L-proline1 Publication

    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.
