... by ring stacking between the indole ring of Trp595 and the proline ring of the substrate, so that all of the studied POP enzymes can be claimed to be specific for proline [4]. It is surprising that ... known. In this analysis we created a conservation profile of POP to study the mutation rates of amino acids involved in substrate binding and to find other essential amino...

... [115] reported the finding of two potential binding sites for HIF-1 in the first intron of the PK-M gene. On the other hand, Yamada and Noguchi [116] reported that there is no HIF-1 binding sequence ... [70]. In melanoma cells, eleva- tion of the cellular Ca 2+ concentration leads to detachment of PFK from the cytoskeleton and thus diminishes the provision of local A...

We analyzed the azide inhibition and determined the inhibition constants for sodium azide, in order to see the effect of the mutation (L559A) on the binding properties ... stability of the trinuclear site is decreased, the binding of azide to the trinuclear site may be decreased. The depletion of the T2 copper and chloride ion may...
