RelMtb is a dual-function enzyme carrying out ATP: GTP/GDP/ITP 3-diphosphoryltransferase and (p)ppGpp 3-diphosphohydrolase reactions. The differential regulation of the opposing activities of RelMtb is dependent on the ratio of uncharged to charged tRNA and the association of enzyme with a complex containing tRNA, ribosomes, and mRNA, i.e. RAC |
