kynureninase; This model describes kynureninase, a pyridoxal-phosphate enzyme. Kynurinine is a Trp breakdown product and a precursor for NAD. In Chlamydia psittaci, an obligate intracellular pathogen, kynureninase makes anthranilate, a Trp precursor, from kynurenine. This counters the tryptophan hydrolysis that occurs in the host cell in response to the pathogen. [Energy metabolism, Amino acids and amines]

Cysteine desulfurase (SufS)-like. This family belongs to the pyridoxal phosphate (PLP)-dependent aspartate aminotransferase superfamily (fold I). The major groups in this CD correspond to cysteine desulfurase (SufS) and selenocysteine lyase. SufS catalyzes the removal of elemental sulfur and selenium atoms from L-cysteine, L-cystine, L-selenocysteine, and L-selenocystine to produce L-alanine; and selenocysteine lyase catalyzes the decomposition of L-selenocysteine.

1.19e-06
Alanine-glyoxylate aminotransferase (AGAT) family. This family belongs to pyridoxal phosphate (PLP)-dependent aspartate aminotransferase superfamily (fold I). The major groups in this CD correspond to alanine-glyoxylate aminotransferase (AGAT), serine-glyoxylate aminotransferase (SGAT), and 3-hydroxykynurenine transaminase (HKT). AGAT is a homodimeric protein, which catalyses the transamination of glyoxylate to glycine, and SGAT converts serine and glyoxylate to hydroxypyruvate and glycine. HKT catalyzes the PLP-dependent transamination of 3-hydroxykynurenine, a potentially toxic metabolite of the kynurenine pathway.

8.16e-06
Aspartate aminotransferase (AAT) superfamily (fold type I) of pyridoxal phosphate (PLP)-dependent enzymes. PLP combines with an alpha-amino acid to form a compound called a Schiff base or aldimine intermediate, which depending on the reaction, is the substrate in four kinds of reactions (1) transamination (movement of amino groups), (2) racemization (redistribution of enantiomers), (3) decarboxylation (removing COOH groups), and (4) various side-chain reactions depending on the enzyme involved. Pyridoxal phosphate (PLP) dependent enzymes were previously classified into alpha, beta and gamma classes, based on the chemical characteristics (carbon atom involved) of the reaction they catalyzed. The availability of several structures allowed a comprehensive analysis of the evolutionary classification of PLP dependent enzymes, and it was found that the functional classification did not always agree with the evolutionary history of these enzymes. Structure and sequence analysis has revealed that the PLP dependent enzymes can be classified into four major groups of different evolutionary origin: aspartate aminotransferase superfamily (fold type I), tryptophan synthase beta superfamily (fold type II), alanine racemase superfamily (fold type III), and D-amino acid superfamily (fold type IV) and Glycogen phophorylase family (fold type V).

3.72e-03
Acetyl ornithine aminotransferase family. This family belongs to pyridoxal phosphate (PLP)-dependent aspartate aminotransferase superfamily (fold I). The major groups in this CD correspond to ornithine aminotransferase, acetylornithine aminotransferase, alanine-glyoxylate aminotransferase, dialkylglycine decarboxylase, 4-aminobutyrate aminotransferase, beta-alanine-pyruvate aminotransferase, adenosylmethionine-8-amino-7-oxononanoate aminotransferase, and glutamate-1-semialdehyde 2,1-aminomutase. All the enzymes belonging to this family act on basic amino acids and their derivatives are involved in transamination or decarboxylation.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
