Protein

4-hydroxyproline 2-epimerase

Gene

BR1792

Organism
Brucella suis biovar 1 (strain 1330)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Allows intracellular utilization of 4-hydroxyproline, one of the major constituents of host collagen, by converting trans-4-hydroxy-L-proline (t4LHyp) to cis-4-hydroxy-D-proline (c4DHyp), which can be further metabolized by intracellular 4-hydroxy-D-proline oxidases. Strong B-cell mitogen. Plays an important role in the regulation of intra- and extracellular amino acid pools, allowing the bacterium to profit from host precursors and enzymatic pathways. Displays no proline racemase activity.2 Publications

Catalytic activityi

Trans-4-hydroxy-L-proline = cis-4-hydroxy-D-proline.2 Publications

Enzyme regulationi

Inhibited by iodoacetate, iodoacetamide and by high amounts (10 mM) of pyrrole-2-carboxylic acid (PYC). Not inhibited by PYC at 1 mM.1 Publication

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.
