The initial optical difference spectrum appears to be the sum of reduced cytochrome b5 and a type II difference spectrum of cytochrome P-450. This initial spectrum is unstable and diminishes in size, with a concurrent shift in peak (424 to 428 nm) and trough (409 and 392 to approx. 400 nm) positions, to yield a stable spectrum identical to the type II spectrum of cytochrome P-450. Thus, in addition to its interaction with cytochrome P-450, n-octylamine causes a reduction of cytochrome b5 which subsequently becomes reoxidized. The casual factor for this unusual spectral interaction occurs in the cytoplasm and appears to be protein-bound. It was also present in similar preparations from the tobacco budworm (Heliothis virescens) but not in those from rat or mouse liver or abdomens from insecticide-resistant or susceptible houseflies (Musca domestica). Microsomes from rat and mouse liver, but not those from housefly abdomens, exhibit similar unusual spectral interactions with n-octylamine when supplemented with the soluble factor from the hornworm.}, number={2}, journal={CHEMICO-BIOLOGICAL INTERACTIONS}, author={KULKARNI, AP and HODGSON, E}, year={1977}, pages={223–237} }

No measurable loss of cytochrome P-450 occurred when dilute suspensions of microsomes in buffered sucrose were stored under nitrogen at −20°C for periods up to 6 months. The type I binding of benzphetamine declined in certain storage media but, at the same time, the type II binding of pyridine remained constant and the type III binding of ethyl isocyanide increased slightly. These findings, as well as the implications of denaturation of cytochrome P-450 to cytochrome P-420, are discussed.}, number={1}, journal={INSECT BIOCHEMISTRY}, author={KULKARNI, AP and HODGSON, E}, year={1976}, pages={89–95} }

The study of type II optical difference spectra using several ligands revealed that the basic requirements for this perturbation are the same as in other animal species, namely, a sterically accessible sp2 or sp3 nitrogen atom. An unusual spectral interaction involving both cytochrome P-450 and cytochrome b5 was observed with n-octylamine and certain other amines. The spectral data are discussed in relation to the current ideas on the spectral characterization of microsomal cytochrome P-450. Type I difference spectra were observed with pinacolone, Bux, malathion and an insecticide synergist sulfoxide. However, this spectral response was not observed with several ligands such as benzphetamine, SKF-525A and other compounds known to be type I with microsomes from other animal species.}, number={4}, journal={INSECT BIOCHEMISTRY}, author={KULKARNI, AP and HODGSON, E}, year={1976}, pages={385–390} }

In addition to this, several other varients of the type III interaction were noted. In general these responses with house fly microsomes were similar to those reported for mammals, although some minor species and strain differences were observed.

The specific activity of cytochrome P-450 was higher in microsomes prepared from isolated abdomens than in those from whole flies. Buffers of low molarity (<0·1 M) caused denaturation of cytochrome P-450 and the optimum pH values, in terms of cytochrome P-450 content, were pH 7·0 and 7·2 for microsomes of Fc and CSMA houseflies respectively.

Guidelines were established to reduce errors in measurement and interpretation of substrate difference spectra. Cytochrome P-420 did not exhibit normal type I and type II difference spectra, however, its presence in microsomes interfered with the evaluation of the type III difference spectra of ethyl isocyanide and pyridine. Some strain specific differences were noted in the oxidized difference spectra of type I and type II ligands and in those obtained with microsomes pretreated with either NADH or NADPH. Microsomes from neither strain exhibited normal type I difference spectra with benzphetamine in the presence of dithionite. The data obtained are discussed in relation to current methodology used with microsomal cytochrome P-450 from insects and other taxonomic groups.}, number={6}, journal={INSECT BIOCHEMISTRY}, author={KULKARNI, AP and HODGSON, E}, year={1975}, pages={679–696} }
