MECHANISTIC STUDIES OF MICROSOMAL NITROSAMINE OXIDATIONS.

MARILYN BETH KROEGER KOEPKE, University of Nebraska - Lincoln

Abstract

Since 1954, when Williams [1] first recognized the presence of a carbon monoxide binding pigment in the liver microsomes, much attention has been focused on the structure and function of this ubiquitous protein. Early investigations by Klingenberg [2] and Garfinkel [3] demonstrated that this pigment in the reduced form would combine with carbon monoxide to form a complex absorbing light strongly at 450 nm. Omura and Sato [4,5] established the hemoprotein nature of the pigment, its relatively ready conversion to an inactive form, in which the reduced hemoprotein-carbon monoxide complex absorbed light maximally at 420 nm (cytochrome P-420), and described millimolar extinction coefficients for the two forms.
