3-BPG [21]. As known to all, glycolysis provides intermediates forbiosynthesis. PGAM1 is involved in these processes through its mutase activity [7]. 1,3-BPG, a highly reactive glycolytic intermediate, also acts
现在咱们已经到了糖酵解的第七步,细胞马上就要合成ATP了。最初的葡萄糖现在已经被分成了两半,每一半现在各带着两个磷酸基团(ATP注:指甘油酸-1,3-二磷酸,1,3-bisphosphoglycerate,1,3-BPG)。磷酸甘油酸激酶接过甘油酸-1,3-二磷酸,将它身上其中一个磷酸基团转移给ADP,一个新鲜的ATP就这样出炉了。与第一个酶...
3-bisphosphoglycerate (1,3-BPG) in the sixth step of glycolysis with an inorganic phosphate as a cofactor. Early studies defined GAPDH as a housekeeping gene due to its ubiquitous expression and abundance in various species [8,9
甘油醛 3-磷酸脱氢酶 (GAPDH) (EC 1.2.1.12) 是一种 NAD+依赖性氧化还原酶,可在糖酵解的第6步中以无机磷酸盐作为辅因子将甘油醛 3-磷酸 (GAP) 转化为 1,3-二磷酸甘油酸 (1,3-BPG)。由于GAPDH在各种物种中的...
These conditions and decreased ATP activate bisphosphoglycerate phosphatase, which returns 2,3-BPG to the glycolysis mainstream. In summary, these conditions favor generation of ATP by causing the conversion of 1,3-BPG directly to 3-PG and returning 2,3-BPG to 3-PG for ATP generation ...
Anaerobic forms of exercise associated with a large blood lactate appearance and greatly elevated catecholamines initially decrease 2,3‐BPG after exercise due to inhibited glycolysis, but there appears to be a delayed increase if sampling is continued into recovery. Aerobic forms of exercise have ...

synthesis. SARS-CoV-2 infection upregulated the levels of two constituents in the non-oxidative PPP branch: transketolase and transaldolase 1. Benfooxythiamine, a transketolase inhibitor, significantly curbed SARS-CoV-2 replication. 2-DG interferes with glycolysis to reduce the material for the PPP....
Some familiar enzymes (from glycolysis, although this is happening in the stroma, not the cytoplasm) now come into play. Phosphoglycerate kinase phosphorylates 3-PG to 1,3-bisphosphoglycerate. 1,3-BPG is then reduced by glyceraldehyde-3-phosphate dehydrogenase to form glyceraldehyde- 3-P. This ...
