Taxonomic identifier

471472 [NCBI]

Taxonomic lineage

Bacteria › Chlamydiae › Chlamydiales › Chlamydiaceae › Chlamydia/Chlamydophila group › Chlamydia

Protein attributes

Sequence length	232 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Binds directly to 23S rRNA. The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release By similarity. HAMAP MF_01318_B Protein L1 is also a translational repressor protein, it controls the translation of the L11 operon by binding to its mRNA By similarity. HAMAP MF_01318_B
Subunit structure	Part of the 50S ribosomal subunit By similarity. HAMAP MF_01318_B
Sequence similarities	Belongs to the ribosomal protein L1P family.
