bifunctional acetylglutamate kinase/N-acetyl-gamma-glutamyl-phosphate reductase, L000000110, YER069W
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

Affinity Capture-MS
An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

The ribosome-associated Mba1 escorts Cox2 from insertion machinery to maturing assembly intermediates.
The three conserved core subunits of the cytochrome c oxidase are mitochondrial-encoded in close to all eukaryotes. The Cox2 subunit spans the inner membrane twice, exposing N- and C-terminus into the intermembrane space. For this the N-terminus is exported cotranslationally by Oxa1 and subsequently undergoes proteolytic maturation in Saccharomyces cerevisiae Little is known about the translocation of the C-terminus but ...
