Large ribosomal subunit assembly factor BipA

UniProtKB accession:  P0A3B2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  A 50S ribosomal subunit assembly protein with GTPase activity, required for 50S subunit assembly at low temperatures, may also play a role in translation. Binds GTP and analogs. Binds the 70S ribosome between the 30S and 50S subunits, in a similar position as ribosome-bound EF-G; it contacts a number of ribosomal proteins, both rRNAs and the A-site tRNA (By similarity). GTPase that impacts interactions between enteropathogenic E.coli (EPEC) and epithelial cells and also has an effect on motility (PubMed:9622352).
