Ações bioquímicas/fisiológicas

L-Tyrosine is a non-essential amino acid with a polar side chain. It is utilized by cells to synthesize proteins that have a role in signal transduction. L-Tyrosine is a proteogenic amino acid that acts as a receiver of phosphate groups that are transferred by kinases.

Enzymatic Assay of Proteinase K with Hemoglobin Substrate

Proteinase K (EC 3.4.21.64) activity can be measured spectrophotometrically using hemoglobin as the substrate. Proteinase K hydrolyzes hemoglobin denatured with urea, and liberates Folin-postive amino acids and peptides. One unit will hydrolyze hemoglobin to produce color equivalent to 1.0 μmol of tyrosine per minute at pH 7.5 at 37 °C (color by Folin & Ciocalteu's Phenol Reagent).
