Explain acid selenocysteine found in the active site

Reference no: EM13501909

The amino acid selenocysteine, found in the active site of various enzymes, is identical to cysteine except the sulfur atom is replaced by a selenium atom. Selenocysteine is said to act as a better nucleophile than Cysteine even though sulfur has a higher electronegativity than selenium.
