chorismate + L-glutamine = 4-amino-4-deoxychorismate + L-glutamate | the enzyme is composed of two parts, PabA and PabB | Escherichia coli | |
chorismate + L-glutamine = 4-amino-4-deoxychorismate + L-glutamate | in the absence of PabA and glutamine, PabB converts ammonia and chorismate into 4-amino-4-deoxychorismate (in the presence of Mg2+) | Escherichia coli | |
chorismate + L-glutamine = 4-amino-4-deoxychorismate + L-glutamate | non linear production of PABA in the ADC synthase-ADC lyase-coupled reaction system, at different glutamine and chorismate concentrations, with limiting PabB | Escherichia coli |
