URA4

Saccharomyces cerevisiae

Dihydroorotase; catalyzes the third enzymatic step in the de novo biosynthesis of pyrimidines, converting carbamoyl-L-aspartate into dihydroorotate

PIGL

Homo sapiens

N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase

SDS

Homo sapiens

L-serine dehydratase/L-threonine deaminase

BNA7

Saccharomyces cerevisiae

Formylkynurenine formamidase; involved in the de novo biosynthesis of NAD from tryptophan via kynurenine

ADE8

Saccharomyces cerevisiae

Phosphoribosyl-glycinamide transformylase; catalyzes a step in the 'de novo' purine nucleotide biosynthetic pathway

ADE6

Saccharomyces cerevisiae

Formylglycinamidine-ribonucleotide (FGAM)-synthetase; catalyzes a step in the 'de novo' purine nucleotide biosynthetic pathway

CHA1

Saccharomyces cerevisiae

Catabolic L-serine (L-threonine) deaminase; catalyzes the degradation of both L-serine and L-threonine; required to use serine or threonine as the sole nitrogen source, transcriptionally induced by serine and threonine

BNA5

Saccharomyces cerevisiae

Kynureninase; required for the de novo biosynthesis of NAD from tryptophan via kynurenine; expression regulated by Hst1p

DCT

Homo sapiens

L-dopachrome tautomerase

DCXR

Homo sapiens

L-xylulose reductase
