Neomorphic enzymatic activity
WebOct 26, 2015 · PTEN is a 403-amino acid protein with five functional domains. The catalytic “P-loop” region (yellow) spans amino acids 123–130 and is completely conserved across a broad range of eukaryotes. The catalytic cysteine residue at position 124 is highlighted in purple, and amino acid 126 is highlighted in green. WebGenetic mutations identified in TCA cycle genes can both disable enzymatic activity, inducing accumulation of specific metabolites, or bring to neomorphic enzymatic activity. Very interestingly, mutations of a specific gene of the TCA cycle are often responsible for predisposition to a particular type of tumor, ...
