Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Transaminase converting glutamate 1-semialdehyde (GSA) to 5-aminolevulinate (ALA). Involved in the biosynthesis of tetrapyrroles.1 Publication

Catalytic activityi

(S)-4-amino-5-oxopentanoate = 5-aminolevulinate.

Cofactori

Pathwayi: protoporphyrin-IX biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes 5-aminolevulinate from L-glutamyl-tRNA(Glu).
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Probable glutamyl-tRNA reductase 3, chloroplastic (HEMA3), Glutamyl-tRNA reductase 2, chloroplastic (HEMA2), Glutamyl-tRNA reductase 1, chloroplastic (HEMA1), Glutamyl-tRNA reductase (AXX17_At1g09980), Glutamyl-tRNA reductase (AXX17_At1g52270), Glutamyl-tRNA reductase (AXX17_At2g27450)
  2. Glutamate-1-semialdehyde 2,1-aminomutase 2, chloroplastic (GSA2), Glutamate-1-semialdehyde 2,1-aminomutase 1, chloroplastic (GSA1)
This subpathway is part of the pathway protoporphyrin-IX biosynthesis, which is itself part of Porphyrin-containing compound metabolism.
