Synthetic tyrosine-phosphorylated peptides were subjected to protein sequence analysis using a gas-phase sequencer and on-line phenylthiohydantoin (PTH) amino acid analysis. Our data show that phosphotyrosine is stable to the gas-phase sequencing chemistry and can be detected as its PTH-derivative during routine sequence analysis without the need of prior tyrosine radiolabeling.

D010669	Phenylthiohydantoin	Thiohydantoin benzene derivative.
D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.

D000595	Amino Acid Sequence	The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.

D014443	Tyrosine	A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin.	L-Tyrosine,Tyrosine, L-isomer,para-Tyrosine,L Tyrosine,Tyrosine, L isomer,para Tyrosine
D019000	Phosphotyrosine	An amino acid that occurs in endogenous proteins. Tyrosine phosphorylation and dephosphorylation plays a role in cellular signal transduction and possibly in cell growth control and carcinogenesis.	Tyrosine-O-phosphate,Tyrosine O phosphate
