Cysteine phytase
WebMay 26, 2015 · The hydrolysis of phytate is achieved by the phytase enzyme, named 3-phytase (EC 3.1.3.8) or 6-phytase (EC 3.1.3.26) depending on the position of the first phosphate group removed. The term 4-phytase (EC 3.1.3.26) found in the literature corresponds to 6-phytase when based on 1D-numbering system instead of 1 L-numbering. WebMay 31, 2013 · The phytases are divided into four homology-based families: histidine acid phosphatases (HAP), β-propeller phytases, cysteine phosphatases and purple acid phosphatases [9]. The majority are HAPs [17], [18] and are part of a large superfamily of phosphatases [19].
