[4HYPE_PSEAE] 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. Cannot use L-proline, trans-3-hydroxy-L-proline (t3LHyp) and pyrrolidone-5-carboxylate (P5C) as substrate.[1][2][3]
