In this work, we show that adenosine 5'-O-(3-thiotriphosphate) (ATP gamma S) is a substrate for yeast inorganic pyrophosphatase (PPase) (EC 3.6.1.1) and further, using chirally labeled [gamma-17O,18O]...
We have used vibrational spectroscopy to study bonding in monosubstituted dianionic phosphates, both to learn more about basic properties intrinsic to this important class of biological substrates and...
It was found that in the case of N-(diisopropylphosphoryl) glutathion (reduced form), 2, N-->S phosphoryl migration took place, but not for N,N-bis(diisopropylphosphoryl) glutathion (oxidized form) or...
From studies using unlabeled phospho-D-glycerate in solutions enriched in H2(18)O, and from experiments involving [18O]phospho-D-glycerate, it is shown that the intramolecular isomerization of 2- and ...
We have studied the effectiveness of polyprenyl-P-mannose and polyprenol-P-glucose as donor substrates for the dolichyl-P-mannose:Man5(GlcNAc)2-PP-dolichol mannosyltransferase and the dolichyl-P-gluco...
BACKGROUND AND OBJECTIVES: In this paper we examined the influence of epidermal growth factor receptor (EGFR) gene mutations on EGFR expression, downstream mediators, and survival in patients with non...
