wild type condition edit

Latest comment: 13 years ago1 comment1 person in discussion

Wild type is refrecne to the genes that produce the enzyme so when you say wild type you mean in a health indivdual. i dont belive this to be correct and if it is , it should be ellbarated on alittle —Preceding unsigned comment added by 131.227.105.67 (talk) 10:26, 28 May 2010 (UTC)Reply

Cofactors of pyruvate kinase edit

Latest comment: 13 years ago1 comment1 person in discussion

Can someone reference the statement that pyruvate kinase requires manganese ion (Mn)? As in Voet Biochemistry text book 3rd edition on pp584, it says Mg2+ and K+.

Missing link of addition of hydrogen from PEP to Pyruvate edit

Latest comment: 13 years ago1 comment1 person in discussion

Can someone add on about where the extra H in pyruvate comes from? It doesn't seem like from water. I think this is always a vague point in this particular reaction analysis of glycolysis pathway. — Preceding unsigned comment added by Otivaeey (talk • contribs) 19:09, 13 February 2011 (UTC)Reply

Adding cancer related content to this page edit

Hi! I am taking a biochemistry course at UCLA and wish to add discussions about how pyruvate cancer is involved in cancer. Does anyone have any thoughts or suggestions? Thanks Tkadali (talk) 05:24, 13 February 2019 (UTC)Reply

PK is not Rate-Limiting in Mammalian Cells edit

Latest comment: 3 years ago1 comment1 person in discussion

The section on Glycolysis/Regulation states that Pyruvate Kinase is rate-limiting. I don't think it is, at least not in mammalian cells, see the paper "Tanner et al, Four Key Steps Control Glycolytic Flux in Mammalian Cells, 2018, Cell Systems". Table 1 in the paper shows that PK (PKM1) has a flux control coefficient of less than 0.1, not exactly limiting. PKM2 is not limiting at all. I've not looked at yeast data or other organisms where PK might well have a higher flux control coefficient. This should be clarified in the text especially given the number of students that are likely to read this page. Rhodydog (talk) 18:20, 28 January 2021 (UTC)Reply
