    Evolutionary links between cytochrome P450 monooxygenases, a superfamily of extraordinarily divergent heme-thiolate proteins catalyzing a wide array of NADPH/NADH- and O2-dependent reactions, are becoming better understood ...

    Native yeast NADPH–cytochrome P450 oxidoreductase (CPR; EC 1.6.2.4) and a soluble derivative lacking 33 amino acids of the NH2-terminus have been overexpressed as recombinant proteins in Escherichia coli. The presence of ...

    The annotated genome of Streptomyces coelicolor A3(2) revealed 18 cytosolic cytochromes P450 (CYPs) with six ferredoxin (fdx) proteins and two soluble ferredoxin reductases (fpr), their putative electron transport proteins. ...
  • Kelly, Steven L.; Lamb, David C.; Jackson, Colin J.; Warrilow, Andrew G. S.; Kelly, Diane E. (Academic Press, 2003)
    The cytochrome P450 (CYP) superfamily of genes and proteins are well known for their involvement in pharmacology and toxicology, but also increasingly for their importance and diversity in microbes. The extent of diversity ...

    The genus Streptomyces produces two-thirds of microbially derived antibiotics. Polyketides form the largest and most diverse group of these natural products. Antibiotic diversity of polyketides is generated during their ...
  • Jackson, Colin J.; Parker, Josie E.; Lamb, David C.; Marczylo, Timothy H.; Kelly, Diane E.; Manning, Nigel L.; Kelly, Steven L. (2003-02-07)
    The genetic locus encoding cytochrome P450 51 (CYP51; P45014DM) in Mycobacterium smegmatis is described here together with confirmation of activity in lanosterol 14α-demethylation. The protein bound azole antifungals with ...
  • Kelly, Steven L.; Waterman, M. R.; Skaug, T.; Jackson, Colin J.; Kelly, Diane E.; Podust, L. M.; Kell, Douglas B.; Song, H. L.; Lamb, David C. (2002-04-09)
    In the present study we describe the complete cytochrome P450 complement, the “CYPome,” of Streptomyces coelicolor A3(2). Eighteen cytochromes P450 (CYP) are described, in contrast to the absence of CYPs in Escherichia ...
  • Waterman, Michael R.; Ishikawa, Jun; Skaug, Tove; Omura, Satoshi; Nelson, David R.; Ikeda, Haruo; Jackson, Colin J.; Kelly, Steven L.; Lamb, David C. (2003-08-01)
    The genus Streptomyces produces about two-thirds of naturally occurring antibiotics and a wide array of other secondary metabolites, including antihelminthic agents, antitumor agents, antifungal agents, and herbicides. The ...
  • Ugochukwu, C. C.; Lamb, David C.; Kaderbhai, Mustak A.; Kelly, Steven L. (2001)
    CYP105D1, a cytochrome P450 from Streptomyces griseus, was appended at its amino terminus to the secretory signal of Escherichia coli alkaline phosphatase and placed under the transcriptional control of the native phoA ...

    Determining the effect of gene deletion is a fundamental approach to understanding gene function. Conventional genetic screens exhibit biases, and genes contributing to a phenotype are often missed. We systematically ...
  • Lamb, David C.; Kelly, Steven L.; Kelly, Diane E. (2001)
    In the year 2001 a collection of yeast strains will be completed that are deleted in the 6000 open reading frames selected as putative genes by the initial bioinformatic analysis of the Saccharomyces cerevisiae genome. The ...
  • Venkateswarlu, K.; Kelly, Steven L.; Kaderbhai, Naheed N.; Lamb, David C.; Kaderbhai, Mustak A.; Kelly, Diane E. (2001-11-01)
    Human sterol 14α-demethylase (P45051; CYP51) catalyzes the oxidative removal of the C32 methyl group of dihydrolanosterol, an essential step in the cholesterol biosynthetic pathway. The reaction is dependent upon NADPH ...
  • Lamb, David C.; Manning, Nigel J.; Jackson, Colin J.; Kelly, Diane E.; Kelly, Steven L. (2003-10-03)
    Understanding fluconazole resistance is important as it emerged as a serious clinical problem for this CYP51, sterol 14α-demethylase, inhibitor. One mechanism, observed first in Saccharomyces cerevisiae, was through defective ...

    Sterol 14α-demethylase encoded by CYP51 is a member of the cytochrome P450 (CYP) superfamily of enzymes and has been shown to have an essential role in sterol biosynthesis in eukaryotes, with orthologues recently being ...
  • Kelly, Steven L.; Lamb, David C.; Marczylo, Timothy H.; Jackson, Colin J.; Kelly, Diane E.; Cannieux, Michel; Ugochukwu, C.; Greetham, Darren (2001)
    Cytochrome P450 51 (CYP51) is sterol 14a-demethylase, known also as Erg11p in yeast. First studied in yeast, where it is one of three CYPs in the genome, it has subsequently gained attention as the only CYP found so far ...
