A gene cluster encoding all of the enzymes for the biosynthesis of the antibiotic pentalenolactone (1) has recently been identified in Streptomyces avermitilis. The biosynthetic gene cluster contains the ptlI (SAV2999) gene which encodes a cytochrome P450 (CYP183A1). PtlI was cloned by PCR and expressed in Escherichia coli as a C-terminal His6-tag protein. Recombinant PtlI bound pentalenene (3) with high affinity (KD = 1.44 +/-0.14 muM). Incubation of recombinant PtlI with (+/-)-3 in the presence of NADPH, E. coli flavodoxin and flavodoxin reductase, and O2 resulted in conversion to a single enantiomer of pentalen-13-al (7), by stepwise allylic oxidation via pentalen-13-ol (6). The steady-state kinetic parameters for the oxidation of pentalenene (3) to pentalen-13-ol (6) were kcat = 0.503 +/-0.006 min-1 and Km = 3.33+/-0.62 muM for 3. << Less
