1.14.11.55
additional information
the cosubstrate 2-oxoglutarate is stoichiometrically decarboxylated during the hydroxylation of the substrate ectoine. CO2 is thereby liberated from 2-oxoglutarate to form succinate. During the hydroxylation reaction, one atom of the atmospheric oxygen molecule is incorporated into succinate, whereas the other atom is incorporated into the hydroxy group formed on ectoine

Virgibacillus salexigens
ectoine production is linearly correlated with the salinity of the growth medium. The formation of 5-hydroxyectoine is primarily a stationary growth phase phenomenon. The transcript levels of the ectABC and ectD genes increase as a function of salinity
