PF00009Elongation factor Tu GTP binding domain (GTP_EFTU)Elongation factor Tu GTP binding domainThis domain contains a P-loop motif, also found in several other families such as Pfam:PF00071, Pfam:PF00025 and Pfam:PF00063. Elongation factor Tu consists of three structural domains, this plus two C-terminal beta barrel domains.Domain
PF11987Translation-initiation factor 2 (IF-2)Translation-initiation factor 2IF-2 is a translation initiator in each of the three main phylogenetic domains (Eukaryotes [1], Bacteria [2] and Archaea [3]). IF2 interacts with formylmethionine-tRNA, GTP, IF1, IF3 and both ribosomal subunits [2].

IF2 interacts with formylmethionine-tRNA, GTP, IF1, IF3 and both ribosomal subunits [2]. Through these interactions, IF2 promotes the binding of the initiator tRNA to the A site in the smaller ribosomal subunit and catalyses the hydrolysis of GTP following initiation-complex formation [2].

PF00189Ribosomal protein S3, C-terminal domain (Ribosomal_S3_C)Ribosomal protein S3, C-terminal domainThis family contains a central domain Pfam:PF00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.Domain

The S4 domain probably mediates binding to RNA.
