EC number 1.2.1.70 | ExPASy NiceZyme view MetaCyc | |
A glutamyl-tRNA reductase (EC 1.2.1.70) is an enzyme that catalyzes the chemical reaction
L-glutamate 1-semialdehyde + NADP+ + tRNAGlu
The 3 substrates of this enzyme are L-glutamate 1-semialdehyde, NADP+, and tRNA(Glu), whereas its 3 products are L-glutamyl-tRNA(Glu), NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, to be specific, those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-glutamate-semialdehyde: NADP+ oxidoreductase (L-glutamyl-tRNAGlu-forming). This enzyme participates in porphyrin and chlorophyll metabolism.
