Protein names

Recommended name:
50S ribosomal protein L29

Gene names

Name:	rpmC
Ordered Locus Names:	b3312, JW3274

Organism

Escherichia coli (strain K12)

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributes

Sequence length	63 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Binds 23S rRNA. It is not essential for growth. HAMAP MF_00374 One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit. Contacts trigger factor (Ref.8). HAMAP MF_00374
Subunit structure	Part of the 50s ribosomal subunit. Contacts protein L23 (Ref.7), trigger factor (Ref.8) and protein nascent chains (Ref.9). Might also contact SecE and probably does contact SecG when the SecYEG translocation complex is docked with the ribosome.
Disruption phenotype	Cells missing both S17 and L29 grow very slowly and have a rather unstable temperature-sensitive phenotype. Ref.8
Sequence similarities	Belongs to the ribosomal protein L29P family.
Mass spectrometry	Molecular mass is 7273.4 Da from positions 1 - 63. Determined by MALDI. Ref.10
Sequence caution	The sequence described in Ref.1 differs from that shown. Reason: Exchange of two tryptic peptides.
