Elongation factor Ts signatures


In prokaryotes elongation factor Ts (EF-Ts) is a component of the elongation cycle of protein biosynthesis. It associates with the EF-Tu.GDP complex and induces the exchange of GDP to GTP, it remains bound to the aminoacyl-tRNA. EF-Tu.GTP complex up to the GTP hydrolysis stage on the ribosome [1].

EF-Ts is also a component of the chloroplast protein biosynthetic machinery and is encoded in the genome of some algal chloroplast [2]. It is also present in mitochondria [3].

As signature patterns for EF-Ts, we selected two conserved regions located in the N-terminal part of the protein.
