Initiation factor 3 (IF-3) (gene infC) is one of the three factors required for the
initiation of protein biosynthesis in bacteria. IF-3 is thought to function as a
fidelity factor during the assembly of the ternary initiation complex which consist of
the 30S ribosomal subunit, the initiator tRNA and the messenger RNA. IF-3 is a basic
protein that binds to the 30S ribosomal subunit . The chloroplast initiation factor IF-3(chl) is a protein that
enhances the poly(A,U,G)-dependent binding of the initiator tRNA to chloroplast ribosomal
30s subunits in which the central section is evolutionary related to the sequence of
bacterial IF-3 .

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry
out SCOP domain assignments to all genomes at the superfamily level.
Alignments of sequences to 4 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.
Browse and view proteins in genomes which have
different domain combinations including a Translation initiation factor IF3, C-terminal domain domain.
Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
There are 4 hidden Markov models representing the Translation initiation factor IF3, C-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
