Autor: W. Theodore Lee, H.Richard Levy

Publikováno v: Protein Science. 1:329-334

Leuconostoc mesenteroides glucose 6-phosphate dehydrogenase (G6PD) was isolated in high yield and purified to homogeneity from a newly constructed strain of Escherichia coli which lacks its own glucose 6-phosphate dehydrogenase gene. Lys-21 is one of

Evidence for an Essential Lysine in Glucose-6-Phosphate Dehydrogenase from Leuconostoc mesenteroides

Autor: Michael Milhausen, H.Richard Levy

Publikováno v: European Journal of Biochemistry. 50:453-461

Pyridoxal 5′-phosphate inhibits glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides reversibly which Ki= 0.04–0.06 mM. This inhibition is competitive with respect to glucose 6-phosphate and non-competitive with respect to NADP+ or NA

Glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides

Autor: Thomas H. Grove, Armana Ishaque, H.Richard Levy

Publikováno v: Archives of Biochemistry and Biophysics. 177:307-316

Glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides utilizes either NAD+ or NADP+ as coenzyme. Kinetic studies showed that NAD+ and NADP+ interact with different enzyme forms (Olive, C., Geroch, M. E., and Levy, H. R. (1971) J. Biol. Che
