A computational strategy for homology modeling, using several protein structures comparison, is described. This strategy implies a formalized definition of structural blocks common to several protein structures, a new program to compare these structures simultaneously, and the use of consensus matri
## Abstract An overview of the COMPACT method for evaluating potential toxicity mediated by cytochrome P450 enzymes is presented. Particular aspects of P450s are described, together with details of QSARs and homology modelling of mammalian P450s associated with foreign compound metabolism. Β© 2001
## Abstract Although vitamin D~3~ is a natural product of a sunlightβmediated process in the skin, the secosteroid's biological function is dependent upon specific cytochrome P450 enzymes that mediate the parent vitamin's bioactivation and inactivation. Cytochrome P450C1 (CYP27B1) is the regulatory
