Mycobacterium tuberculosis DosS is critical for the induction of M. tuberculosis dormancy genes in response to nitric oxide (NO), carbon monoxide (CO), or hypoxia. These environmental stimuli, which are sensed by the DosS heme group, result in autoph

The second-line antitubercular drugs thiacetazone (TAZ) and ethionamide (ETA) are bioactivated by the mycobacterial enzyme EtaA. We report here that human flavin-containing monooxygenase 2.1 (FMO2.1), which is expressed predominantly in the lung, cat

The crystal structure of a cytochrome P450 from the thermoacidophile Picrophilus torridus, CYP231A2 (PTO1399), has been solved. This structure reveals a wide open substrate access channel. To better understand ligand-induced structural transitions in

Epothilones are potential anticancer drugs that stabilize microtubules by binding to tubulin in a manner similar to paclitaxel. Cytochrome P450epoK (P450epoK), a heme containing monooxygenase involved in epothilone biosynthesis in the myxobacterium S

Inducible (iNOS) and constitutive (eNOS, nNOS) nitric-oxide synthases differ in their Ca2+-calmodulin (CaM) dependence. iNOS binds CaM irreversibly but eNOS and nNOS, which bind CaM reversibly, have inserts in their reductase domains that regulate el

The resistance of Mycobacterium tuberculosis to isoniazid is commonly linked to inactivation of a catalase-peroxidase, KatG, that converts isoniazid to its biologically active form. Loss of KatG is associated with elevated expression of the alkylhydr

Defining the conformational states of cytochrome P450 active sites is critical for the design of agents that minimize drug-drug interactions, the development of isoform-specific P450 inhibitors, and the engineering of novel oxidative catalysts. We us

To clarify the role of the autoinhibitory insert in the endothelial (eNOS) and neuronal (nNOS) nitric-oxide synthases, the insert was excised from nNOS and chimeras with its reductase domain; the eNOS and nNOS inserts were swapped and put into the no

Five conserved histidine residues are found in the human endothelial nitric-oxide synthase (NOS) heme domain: His-420, His-421, and His-461 are close to the heme, whereas His-146 and His-214 are some distance away. To investigate whether the histidin

The primary sequences of the three mammalian nitric- oxide synthase (NOS) isoforms differ by the insertion of a 52–55-amino acid loop into the reductase domains of the endothelial (eNOS) and neuronal (nNOS), but not inducible (iNOS). On the basis o
