Research output: Contribution to journalArticlepeer-review


The metabolism of ethylbenzene by cytochrome P450cam was analyzed by experimental and theoretical methods. The present experiments indicate that ethylbenzene is hydroxylated almost exclusively at the secondary ethyl carbon with about a 2:1 ratio of R:S product. Several molecular dynamics trajectories were performed with different starting conformations of ethylbenzene in the active site of P450cam. The stereochemistry of hydroxylation predicted from the molecular dynamics simulations was found to be in good agreement with the observed products.
