Phenylalanine and tyrosine structure
Some of the tyrosine residues can be tagged (at the hydroxyl group) with a phosphate group (phosphorylated) by protein kinases. In its phosphorylated form, tyrosine is called phosphotyrosine. Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. Phosphotyrosine can be detected through specific antibodies. … WebApr 23, 2024 · Structurally, phenylalanine is closely related to dopamine, epinephrine and tyrosine.
