The substrate specificity of L-proline 4-hydroxylase, a 2-oxoglutarate dependent dioxygenase from Streptomyces griseoviridus P8648, was investigated. Preliminary assays measuring turnover of 2-oxoglutarate indicated 3,4-dehydro-L-proline was an efficient substrate. The identity of the product was shown to be 2S,3R,4S-epoxy-L-proline by comparison with synthetic 2S,3R,4S- and 2S,3S,4R-epoxy-L-prolines.
