What it does, reaction by reaction

1 reactions

Transamination Amino Acid & Nitrogen Metabolism · Cytosol + mitochondrion

step 1 Reversible

Amino acid + enzyme-bound pyridoxal phosphate (E-PLP) → corresponding α-keto acid + enzyme-bound pyridoxamine phosphate (E-PMP)

Converts Enzyme-bound pyridoxal phosphate into Enzyme-bound pyridoxamine phosphate

Notes

An aminotransferase (transaminase) forms an external aldimine with the amino acid and transfers its amino group to PLP. PLP (pyridoxal 5′-phosphate; vitamin B6) is essential; this reversible first half-reaction uses no ATP and no free ammonia is produced.
