Protein
4-hydroxyproline epimerase
Gene
BPSS0332
Organism
Burkholderia pseudomallei (strain K96243)
Status
Reviewed - 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 4-hydroxy-L-proline to 4-hydroxy-D-proline, which can be further metabolized by intracellular 4-hydroxy-D-proline oxidases.

Catalytic activityi

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

Enzyme regulationi

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

Kineticsi

  1. KM=14.4 mM for 4-hydroxy-L-proline1 Publication
  2. KM=17.1 mM for 4-hydroxy-D-proline

Vmax=2.1 µM/sec/mg enzyme with L-proline as substrate (at 37 degrees Celsius)

Vmax=2.4 µM/sec/mg enzyme with D-proline as substrate (at 37 degrees Celsius)
