Acetylglutamate kinase and N-acetyl-gamma-glutamyl-phosphate reductase; N-acetyl-L-glutamate kinase (NAGK) catalyzes the 2nd and N-acetyl-gamma-glutamyl-phosphate reductase (NAGSA), the 3rd step in arginine biosynthesis; synthesized as a precursor which is processed in the mitochondrion to yield mature NAGK and NAGSA; enzymes form a metabolon complex with Arg2p; NAGK C-terminal domain stabilizes the enzymes, slows catalysis and is involved in feed-back inhibition by arginine

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.415 | 7.66E-140 | YOL140W | ARG8 | hom | Acetylornithine aminotransferase, catalyzes the fourth step in the biosynthesis of the arginine precursor ornithine |
0.254 | 1.30E-50 | YGR122C-A_d | YGR122C-A_d | hom | Dubious open reading frame unlikely to encode a functional protein, similar to YLR334C and YOL106W |
0.226 | 4.76E-40 | YJL088W | ARG3 | hom | Ornithine carbamoyltransferase (carbamoylphosphate:L-ornithine carbamoyltransferase), catalyzes the sixth step in the biosynthesis of the arginine precursor ornithine |
0.222 | 1.34E-38 | YER068C-A_d | YER068C-A_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.217 | 6.46E-37 | YKL151C | YKL151C | hom | NADHX dehydratase; converts (S)-NADHX to NADH in an ATP-dependent manner; homologous to Carkd in mammals, and the C-terminal domain of YjeF in E.coli; enzyme is widespread in eukaryotes, prokaryotes and archaea; YKL151C promoter contains STREs (stress response elements) and expression is induced by heat shock or methyl methanesulfonate; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; protein abundance increases in response to DNA replication stress |
0.216 | 7.61E-37 | YBR265W | TSC10 | het | 3-ketosphinganine reductase, catalyzes the second step in phytosphingosine synthesis, essential for growth in the absence of exogenous dihydrosphingosine or phytosphingosine, member of short chain dehydrogenase/reductase protein family |
0.215 | 1.77E-36 | YOR130C | ORT1 | hom | Ornithine transporter of the mitochondrial inner membrane, exports ornithine from mitochondria as part of arginine biosynthesis; human ortholog is associated with hyperammonaemia-hyperornithinaemia-homocitrullinuria (HHH) syndrome |
0.193 | 2.06E-29 | YBR041W | FAT1 | hom | Very long chain fatty acyl-CoA synthetase and long chain fatty acid transporter; activates imported fatty acids with a preference for very long lengths (C20-C26); has a separate function in the transport of long chain fatty acids |
0.187 | 1.15E-27 | YJR148W | BAT2 | hom | Cytosolic branched-chain amino acid (BCAA) aminotransferase, preferentially involved in BCAA catabolism; homolog of murine ECA39; highly expressed during stationary phase and repressed during logarithmic phase |
0.182 | 2.68E-26 | YOL058W | ARG1 | hom | Arginosuccinate synthetase, catalyzes the formation of L-argininosuccinate from citrulline and L-aspartate in the arginine biosynthesis pathway; potential Cdc28p substrate |
0.168 | 1.40E-22 | YBR062C_p | YBR062C_p | hom | Protein of unknown function that interacts with Msb2p; may play a role in activation of the filamentous growth pathway. |
0.159 | 2.22E-20 | YJL122W | ALB1 | hom | Shuttling pre-60S factor; involved in the biogenesis of ribosomal large subunit; interacts directly with Arx1p; responsible for Tif6p recycling defects in absence of Rei1p |
0.158 | 3.77E-20 | YJL071W | ARG2 | hom | Acetylglutamate synthase (glutamate N-acetyltransferase), mitochondrial enzyme that catalyzes the first step in the biosynthesis of the arginine precursor ornithine; forms a complex with Arg5,6p |
0.157 | 4.86E-20 | YDR063W | AIM7 | hom | Protein that interacts with Arp2/3 complex to stimulate actin filament debranching and inhibit actin nucleation; has similarity to Cof1p and also to human glia maturation factor (GMF); null mutant displays elevated mitochondrial genome loss |
