Preparation and Storage

Background: Kynureninase

Kyureninase (KYNU, a hydrolase that acts on dog [Greek: kyon] urine [Greek: ouron]) is a 50-55 kDa member of the kyureninase family of enzymes.  It is a pyridoxal phosphate-dependent cytosolic hydrolase that occurs in a variety of cell types, including hepatocytes and macrophages.  Kyureninase participates in the metabolism of tryptophan.  Dietary Trp is either incorporated into protein, or metabolized into niacin, serotonin or NAD.  Kyureninase catalyzes one of two steps that lead to the formation of a key downstream intermediate called 3-hydroxyanthranilic acid.  Mouse Kyureninase is 464 amino acids (aa) in length.  It contains one large catalytic site (aa 24-462), and typically functions as a noncovalent homodimer.  There are at least two potential isoform variants.  One contains a three aa substitution for aa 425-464, while another possesses a 22 aa substitution for aa 302-464.  Full-length mouse Kyureninase shares 92% and 83% aa sequence identity with rat and human Kyureninase, respectively.
