Cysteine synthase/cystathionine beta-synthase, pyridoxal-phosphate attachment site (IPR001216) Cysteine synthase (CSase) is the enzyme responsible for the formation of cysteine from O-acetyl-serine and hydrogen sulphide with the concomitant release of acetic acid. In bacter...

Germin, manganese binding site (IPR019780) Germins and germin-like proteins are a family of hexameric ubiquitous plant glycoproteins. They are not restricted to germinating grains as initially thought and therefore called ...

Protein kinase, ATP binding site (IPR017441) Protein phosphorylation, which plays a key role in most cellular activities, is a reversible process mediated by protein kinases and phosphoprotein phosphatases. Protein kinases c...

Pyridoxal-phosphate binding site (IPR021115) Pyridoxal phosphate is the active form of vitamin B6 (pyridoxine or pyridoxal). Pyridoxal 5'-phosphate (PLP) is a versatile catalyst, acting as a coenzyme in a multitude of reacti...

RNA polymerases, subunit N, zinc binding site (IPR020789) In eukaryotes, there are three different forms of DNA-dependent RNA polymerases transcribing different sets of genes. Each class of RNA polymerase is an assemblage of ten to twelv...

Oxidoreductase, molybdopterin binding site (IPR022407) A number of different eukaryotic oxidoreductases that require and bind a molybdopterin cofactor have been shown to share a few regions of sequence similarity. These enzymes includ...

Porphobilinogen deaminase, dipyrromethane cofactor binding site (IPR022419) This entry represents the region around a cysteine residues that is conserved in porphobilinogen deaminases from various prokaryotic and eukaryotic sources. The sulphur atom of th...

Sigma-54 interaction domain, ATP-binding site 1 (IPR025662) Some bacterial regulatory proteins activate the expression of genes from promoters recognised by core RNA polymerase associated with the alternative sigma-54 factor. These have a ...

Xylulose 5-phosphate/Fructose 6-phosphate phosphoketolase, thiamine diphosphate binding site (IPR019789) Phosphoketolases (PK) are key enzymes of the pentose phosphate pathway of heterofermentative and facultative homofermentative lactic acid bacteria and of the D-fructose 6-phosphat...

Aminotransferase class-V, pyridoxal-phosphate binding site (IPR020578) Aminotransferases share certain mechanistic features with other pyridoxal- phosphate dependent enzymes, such as the covalent binding of the pyridoxal- phosphate group to a lysine ...
