Organism

Escherichia coli (strain K12) [Reference proteome] [HAMAP]

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia › Escherichia coli

Protein attributes

Sequence length	104 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	One of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit. It is not thought to be involved in the functions of the mature 50S subunit in vitro. Ref.6 One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit. Ref.6
Subunit structure	Part of the 50S ribosomal subunit. Might contact the SecYEG translocation complex when it is docked with the ribosome. Ref.8
Sequence similarities	Belongs to the ribosomal protein L24P family.
Mass spectrometry	Molecular mass is 11186.5 Da from positions 2 - 104. Determined by MALDI. Ref.9
