Re: Chemistry Behind Substrate Level Phosphorylation «Reply #1 on:January 24, 2016, 02:13:07 PM » I think the energy comes from the other reaction. For example: In this case, the exergonic keto-enol tautomerization of piruvate can drive the reaction to the right and form ATP. ...
Provide one example of how substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation are used in a biological cell. a. Compare the processes of substrate-level phosphorylation, oxidative phosphorylation and photophosphorylation to make ATP. b. How are they different? Si...
The negative impact of -ketoglutarate dehydrogenase complex deficiency on matrix substrate-level phosphorylation A decline in alpha-ketoglutarate dehydrogenase complex (KGDHC) activity has been associated with neurodegeneration. Provision of succinyl-CoA by KGDHC is e... G Kiss,C Konrad,J Doczi,......
Analysis of several published datasets using this pipeline identified specific kinases that are activated by various perturbations. For example, after acute treatment of NIH3T3 cells with PDGF37, the most upregulated Tyr phosphorylation motifs corresponded to those of the PDGF receptor isoforms (Fig.3b...

Many enzymes are regulated byphosphorylation.A phosphate group is attached to the enzyme by another enzyme, called aprotein kinase.When the enzyme is phosphorylated it changes its shape and thus its activity. Phosphorylation activates some enzymes and inactivates others; by this means one protein kin...
For example, the predicted E3 recognizing domain of “TP53 DNA-binding domain” was reported to interact with the E3 of WWP1 17 (Enrichment ratio: 7.21). We used two thirds of the GSP to define enriched domain pairs and the remaining to calculate LRs. We repeated this process three times...
The critical thing to note here is that the first representation requires the state variables themselves (e.g. the depolarization of membranes in all cell compartments, the configuration of every channel, the phosphorylation status of every enzyme, the expression of every gene product and so on)....
