GSH S-transferase activity toward CDNB (1-chloro-2,4-dinitrobenzene) was detected in the egg, and increased throughout the larval stages and was the highest in the 2 day old fifth instar larvae. GSH S-transferase activity toward DCNB (1,2-dichloro-4-nitrobenzene) could only be detected in the 2 day old fourth instar larvae, and the 2 day old fifth instar larvae. Enzyme activity using CDNB and DCNB as substrates was found in different tissues of the 2 day old fifth instar larvae, i.e. fat body, gut and cuticle. The fat body contained the highest enzyme activity for both substrates. The Km values for CDNB conjugation in different stages of larval development and in the different tissues of the 2 day old fifth instar larvae, was approx. 0.24 mM. The enzyme responsible for CDNB-conjugation was purified 48 fold by GSH-agarose affinity chromatography. SDS gel electrophoresis and chromatofocusing resolved only one isozyme which is a homodimer, consisting of two equal size subunits having 23,900 mol. wt, with a pI value of 8.0.}, number={8}, journal={INSECT BIOCHEMISTRY}, author={CHIEN, C and DAUTERMAN, WC}, year={1991}, pages={857–864} }
