Furthermore, the allosteric regulation of PFK2 is very similar to the regulation of PFK1. [20] High levels of AMP or phosphate group signifies a low energy charge state and thus stimulates PFK2. On the other hand, a high concentration of phosphoenolpyruvate (PEP) and citrate signifies that there is a high level of biosynthetic precursor and ...
PFK exists as a homotetramer in bacteria and mammals (where each monomer possesses 2 similar domains) and as an octomer in yeast (where there are 4 alpha- (PFK1) and 4 beta-chains (PFK2), the latter, like the mammalian monomers, possessing 2 similar domains [3]). This protein may use the morpheein model of allosteric regulation. [5]

Allosteric regulation of an enzyme. In the fields of biochemistry and pharmacology an allosteric regulator (or allosteric modulator) is a substance that binds to a site on an enzyme or receptor distinct from the active site, resulting in a conformational change that alters the protein's activity, either enhancing or inhibiting its function.
President Joe Biden sat down with TIME for an exclusive interview. Here's a fact-check of some of his statements.
Misleading videos and false claims that President Joe Biden wandered off aimlessly from the G7 conference last week continued to go viral despite debunkings and fact-checks that tried to correct ...
Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7.1.11) of glycolysis.It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors.
