일반 설명
ATP:pyruvate 2-O-phosphotransferase
Pyruvate kinase has a molar mass of 237,000 and exists as a tetramer. Each polypeptide chain of this tetramer has a molar mass of 57,200. The enzyme contains two identical catalytic particles called protomers. Each of these protomers contains two polypeptide chains. Each protomer contains one site each for Mn2+ and phosphoenolpyruvate.

애플리케이션
Pyruvate kinase has been used to measure ATPase activity and in the determination of adenylate concentration.
생화학적/생리학적 작용
Pyruvate kinase catalyzes the irreversible conversion of P-enolpyruvate and ADP to pyruvate and ATP with the utilization of a proton. The first step is the transfer of phosphate group from P-enolpyruvate to ADP with the formation of bound enolate of pyruvate and ATP. In the second step, a proton is added to enolate to generate the keto form of pyruvate. Apart from this, the enzyme exhibits other activities, such as ATP- and bicarbonate-dependent ATPase, phosphorylation of fluoride and hydroxylamine, ATP-dependent phosphorylation of glycolate, and decarboxylation of oxaloacetate.

Chromatin remodellers are ATP-dependent motor proteins that physically reposition and reorganize nucleosomes. Chd1 and Iswi-type remodellers possess a DNA-binding domain (DBD) needed for efficient nucleosome mobilization; however, it has not been clear how this domain physically contributes to remodelling.

Sulphur, as a constituent of amino acids (cysteine and methionine), iron-sulphur clusters, proteins, membrane sulpholipids, glutathione, glucosinolates, coenzymes, and auxin precursors, is essential for plant growth and development. Absence or low sulphur concentration in the soil results in severe growth
