cellular organisms › Bacteria › Firmicutes › Bacilli › Lactobacillales › Streptococcaceae › Lactococcus › Lactococcus lactis › Lactococcus lactis subsp. lactis

Protein attributes

Sequence length	119 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit By similarity. HAMAP-Rule MF_00382
Sequence similarities	Belongs to the ribosomal protein L20P family.
