Abstract excerpt

Fifty-four homolog (Ffh) and FtsY are the central components of the signal recognition particle secretory pathway of bacteria. In this study, the core domain and active sites of FtsY and Ffh from Streptomyces coelicolor, which are responsible for guanosine triphosphate (GTP) hydrolysis, were identified using site-directed mutagenesis. Mutations were introduced to the conserved GXXGXGK loop of the putative GTP...
