Amino Acid Catabolism Overview (glucogenic vs. ketogenic amino acids; brief overview of branched-chain amino acid catabolism and phenylalanine/tyrosine catabolism as representative examples) Amino Acid & Nitrogen Metabolism · Cytosol + mitochondrion

step 10 Reversible

L-tyrosine + α-ketoglutarate ⇌ 4-hydroxyphenylpyruvate + glutamate

Converts Tyrosine Alpha-ketoglutarate into 4-Hydroxyphenylpyruvate Glutamate

› Notes

Tyrosine aminotransferase catalyzes this PLP-dependent, reversible reaction. Its activity is induced in liver by glucocorticoids during catabolic states.
