Its function is to phosphorylate glucose releasing glucose-6-phosphate (G6P) as the product. 其功能是磷酸化葡萄糖释放葡萄糖-6-磷酸(G6P)作为产物。 LASER-wikipedia2 It is these that seem to represent the actual sites of oxidative phosphorylation. 看来这些基粒就是进行氧化磷酸化的实际 第十...
(negative feedback) is a pertinent example. Although neither of these metabolites takes part in the reaction catalysed by phosphorylase, thepresence of glucose-6-phosphate signals metabolic sufficiency, while 5′-AMP signals hunger. Both can be described asallosteric effectors, interacting with the...
From a strictly metabolic standpoint, fermentations are microbially catalysed catabolic reactions in which a substrate is broken down in the absence of an external electron acceptor (such as oxygen, nitrate, or sulphate), generating energy by substrate-level phosphorylation (El-Mansi et al....
Glucose-6-phosphate and Na-尾-glycerophate hydrolysis reactions seem to be catalysed by the same enzyme, since both activities exhibit the same distribution in a subcellular fractionation of the gland. Furthermore, as these activities are principally recovered in the subcellular fraction enriched in ...

Phosphoglucomutase (PGM) catalyses the conversion of glucose-1-phosphate (glucose-1-P) to glucose-6-P ( Lee et al., 2014 ). HK catalyses hexose (such as glucose, fructose) phosphorylation to generate hexose-6-phosphate (hexose-6-P) ( Magnani et al., 1992 ), which is the initial ...
Coherent regulon activation depends on multisite phosphorylation of Whi5, SBF and MBF, catalysed by Cln–Cdk1 complexes. A discrete stochastic module calculates the probability distributions of the different phosphorylation states of the DNA-bound SBF (SBF–Whi5 complex) and MBF transcrip- tional ...
Phosphorylation on these residues is associated both with inhibition of insulin-induced tyrosine phosphorylation of IRS proteins and with facilitation of the effects of insulin [4]. Phosphorylation catalysed by protein kinase C (PKC) isozymes [5, 6], c-Jun N-terminal kinase (JNK) [7], ...
Phosphorylation: Phosphorylation refers to multiple metabolic processes within cells, which occur as part of the organism's use of resources. These can be divided into substrate-level phosphorylation and oxidative phosphorylation, both of which produce adenosine triphosphate (ATP). ...
Here, we describe the detection of FRD activity in human cancer cells. The activity level was low, but distinct, and it increased significantly when the cells were cultured under hypoxic and glucose-deprived conditions. Treatment with phosphatase caused the dephosphorylation of flavoprotein subunit (...
