Adenosine triphosphate-dependent transport of doxorubicin, daunomycin, and vinblastine in human tissues by a mechanism distinct from the P-glycoprotein.

Awasthi, S, Singhal, S S, Srivastava, S K, Zimniak, P, Bajpai, K K, Saxena, M, ...

Previous studies have demonstrated that a human glutathione conjugate transporter, designated as dinitrophenyl-S-glutathione ATPase (DNP-SG ATPase), catalyzed ATP hydrolysis in the presence of...

Glucuronidation of 6 alpha-hydroxy bile acids by human liver microsomes.

Radomińska-Pyrek, A, Zimniak, P, Irshaid, Y M, Lester, R, Tephly, T R, St Pyrek, J

The glucuronidation of 6-hydroxylated bile acids by human liver microsomes has been studied in vitro; for comparison, several major bile acids lacking a 6-hydroxyl group were also investigated....

Human liver steroid sulphotransferase sulphates bile acids.

Radominska, A, Comer, K A, Zimniak, P, Falany, J, Iscan, M, Falany, C N

The sulphation of bile acids is an important pathway for the detoxification and elimination of bile acids during cholestatic liver disease. A dehydroepiandrosterone (DHEA) sulphotransferase has been...

Distinct forms of cytochrome P-450 are responsible for 6 beta-hydroxylation of bile acids and of neutral steroids.

Zimniak, P, Holsztynska, E J, Radominska, A, Iscan, M, Lester, R, Waxman, D J

Cytochrome P-450-dependent 6 beta-hydroxylation of bile acids in rat liver contributes to the synthesis of the quantitatively important pool of 6-hydroxylated bile acids, as well as to the...

Role of glutamine synthetase in the uptake and metabolism of methylammonium by Azotobacter vinelandii.

Barnes, E M, Zimniak, P, Jayakumar, A

Methylammonium is a substrate for the ammonium transport system of Azotobacter vinelandii. During cellular uptake methylammonium is rapidly converted to a less polar metabolite (E. M. Barnes, Jr.,...

Role of glutamine synthetase in the uptake and metabolism of methylammonium by Azotobacter vinelandii.

Barnes, E M, Zimniak, P, Jayakumar, A

Methylammonium is a substrate for the ammonium transport system of Azotobacter vinelandii. During cellular uptake methylammonium is rapidly converted to a less polar metabolite (E. M. Barnes, Jr.,...
