GatB (Q9VCD0; CG5463) review notes

Identity

• GatB/GatE-family B subunit of mitochondrial GatCAB (human GATB/PET112 ortholog); ATP-dependent
  kinase and amidation of Glu-tRNA(Gln). [file:DROME/GatB/GatB-uniprot.txt "This subunit probably recognizes tRNA(Gln)"].
• Named in PMID:26761199.
• No fly experimental data; annotations are IEA/IBA/ISS.

Decisions

• As for GatA: complex, mitochondrion, GO:0050567 (enables IEA and contributes_to IBA/ISS) accepted;
  obsolete GO:0070681 -> GO:0043685; mitochondrial translation non-core; generic catalytic
  activity -> GO:0050567; ligase and C-N ligase parents non-core.

Deep research (falcon)

• Human data: [file:DROME/GatB/GatB-deep-research-falcon.md "depletion of GatCAB accumulated Glu–tRNA^Gln while mitochondrial tRNA^Glu remained aminoacylated"].
