Evidence for cAMP-mediated control of isoleucyl-tRNA synthetase formation in Escherichia coli K-12.

A L Williams, R S Barnett.   

Abstract

The ability of cAMP to inhibit isoleucyl-tRNA synthetase (IRS) formation has been demonstrated in wild type K-12 Escherichia coli and two adenyl-cyclase (cya) mutants. cAMP appeared not to have any effect on either the valyl- or arginyl-tRNA synthetase (VRS and ARS respectively). Addition of cAMP led to a reduction in rate of IRS synthesis but not VRS or ARS. Furthermore, derepression of IRS and VRS by isoleucine limitation was completely prevented by cAMP.
