Names and origin

Protein names

Recommended name:
Peptide chain release factor 3
Short name=RF-3

Gene names

Name:	prfC
Synonyms:	miaD, tos
Ordered Locus Names:	b4375, JW5873

Organism

Escherichia coli (strain K12)

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributes

Sequence length	529 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Increases the formation of ribosomal termination complexes and stimulates activities of RF-1 and RF-2. It binds guanine nucleotides and has strong preference for UGA stop codons. It may interact directly with the ribosome. The stimulation of RF-1 and RF-2 is significantly reduced by GTP and GDP, but not by GMP. HAMAP MF_00072
Subcellular location	Cytoplasm HAMAP MF_00072.
Sequence similarities	Belongs to the GTP-binding elongation factor family. PrfC subfamily.
