physiological function | glutathione synthetase binds to transcription factor TnrA in its feedback-inhibited form, and also in its non-feedback-inhibited form, although less efficiently. TnrA forms either a stable soluble complex with GlnK in the absence of transmembrane ammonium transporter AmtB, or constitutively binds to glutathione synthetase in the absence of regulatuor GlnK. In vitro, the TnrA C-terminus is responsible for interactions with either glutathione synthetase or GlnK, and this region appears also to mediate proteolysis, suggesting that binding of GlnK or glutathione synthetase protects TnrA from degradation | Bacillus subtilis |
