Popis: | Oxidation of (+) camphor by cytochrome P-450soy-enriched intact cells of Streptomyces griseus resulted in the formation of one major and several minor metabolites. The minor metabolites were identified as 3-endo-hydroxycamphor (2%), 5-endo-hydroxycamphor (7%), 5-exo-hydroxycamphor (9%), 2,5-diketobornane (2%), and camphorquinone (3%). The major metabolite was isolated and conclusively identified as 6-endo-hydroxycamphor (60%). When supplemented with NADPH, spinach ferredoxin:NADP oxidoreductase and spinach ferredoxin, homogeneous preparations of cytochrome P-450soy oxidized camphor to a mixture of 3-endo-, 5-endo-, 5-exo-and 6-endo-hydroxycamphor. The data presented indicates that cytochrome P-450soy resembles its mammalian counterparts in its lack of regio- and stereospecificity in camphor oxidation. |
