Summary
Mg(2+) stimulon-PhoPQ regulon, EvgAS-PhoPQ cascade enhanced expression subset. [More information is available at EcoGene: EG10432]. Glutamate-1-semialdehyde aminotransferase catalyzes the pyridoxal 5'-phosphate-dependent reaction which converts GSA to delta-aminolevulinate (ALA). [More information is available at EcoCyc: EG10432].
