Descrizione generale
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.[1]

Applicazioni
Azioni biochim/fisiol
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.[4]

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

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.
