Autor: Kenneth J. Gruys, James A. Sikorski, R. D. Sammons, Karen S. Anderson, Kenneth A. Johnson

Publikováno v: Biochemistry. 34(19)

Numerous studies have confirmed that glyphosate forms a tight ternary complex with EPSP synthase and shikimate 3-phosphate. It has been proposed [Anton, D., Hedstrom, L., Fish, S., & Abeles, R. (1983) Biochemistry 22, 5903-5908; Steinrucken, H. C., &

Synthesis of Rp and Sp [alpha-18O]ADP from Sp and Rp beta-cyanoethyl-adenosine 5'[1-thiodiphosphate]

Autor: P A Frey, R D Sammons

Publikováno v: Journal of Biological Chemistry. 257:1138-1141

The reaction of adenosine 5'[1-thio-2-cyanoethyl diphosphate], beta-cyanoethyl-ADP alpha S, with cyanogen bromide in aqueous solution near neutrality leads to the formation of adenosine 5'-[2-cyanoethyl diphosphate], beta-cyanoethyl-ADP, in good yiel

Publikováno v: Journal of Biological Chemistry. 257:15047-15053

The stereochemical configuration of the Mn(II) . ADP complex at the active site of creatine kinase has been elucidated by EPR using chirally labeled [alpha-17O]ADP. Superhyperfine coupling between the 17O nucleus and Mn(II) produces a characteristic

Stereochemical control over Mn(II)-thio versus Mn(II)-oxy coordination in adenosine 5'-O-(1-thiodiphosphate) complexes at the active site of creatine kinase

Autor: P J Goodhart, R D Sammons, George H. Reed, Geoffrey W. Smithers, Russell LoBrutto

Publikováno v: Biochemistry. 28(4)

The stereochemical configurations of the Mn(II) complexes with the resolved epimers of adenosine 5'-O-(1-thiodiphosphate) (ADP alpha S), bound at the active site of creatine kinase, have been determined in order to assess the relative strengths of en

Identification of the reactive cysteines of Escherichia coli 5-enolpyruvylshikimate-3-phosphate synthase and their nonessentiality for enzymatic catalysis

Autor: S R, Padgette, Q K, Huynh, S, Aykent, R D, Sammons, J A, Sikorski, G M, Kishore

Publikováno v: The Journal of biological chemistry. 263(4)

Reaction of 5-enolpyruvylshikimate-3-phosphate synthase of Escherichia coli with the thiol reagent 5,5'-dithiobis-(2-nitrobenzoic acid) (DTNB) leads to a modification of only 2 of the 6 cysteines of the enzyme, with a significant loss of its enzymati
