Proline dehydrogenase

Proline (Pro) dehydrogenase (ProDH) potentiates the oxidative burst and cell death of the plant Hypersensitive Response (HR) by mechanisms not yet elucidated. ProDH converts Pro into Δ1 pyrroline-5-carboxylate (P5C) and can act together with P5C dehydrogenase (P5CDH) to produce Glu, or with P5C reductase (P5CR) to regenerate Pro and thus stimulate the Pro/P5C cycle.

Investigations of protein–solute interactions typically show that osmolytes favor native conformations. In this study, the effects of representative compatible and counteracting osmolytes on the reactivationof lactate dehydrogenase from two different conformational states were explored. Contrary to expectations, proline and trimethylamine oxide inhibited both the initial time course and the extent of reactivation of lactate dehydrogenase from bovine heart following dena-turation in guanidine hydrochloride, as well as following inactivation at pH 2.3.

Two distinguishable activity bands for dye-linkedl-proline dehydrogenase (PDH1 and PDH2) were detected when crude extract of the hyperthermo-philic archaeonPyrococcus horikoshiiOT-3 was run on a polyacrylamide gel. After purification, PDH1 was found to be composed of two different subunits with molecular masses of 56 and 43 kDa, whereas PDH2 was composed of four different subunits with molecular masses of 52, 46, 20 and 8 kDa.

Two ORFs encoding a protein related to bacterial dimethylglycine oxidase were cloned from Pyrococcus furiosus DSM 3638. The protein was expressed in Escherichia coli, purified, and shown to be a flavoprotein amine dehydrogenase. The enzyme oxidizes the secondary aminesl-proline, l-pipecolic acid and sarcosine, with optimal catalytic activity towards l-proline.
