UniProt functional annotation for Q9LWB5

UniProt code: Q9LWB5.

Organism: Spinacia oleracea (Spinach).
Taxonomy: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; Caryophyllales; Chenopodiaceae; Chenopodioideae; Anserineae; Spinacia.
 
Function: Component of the chloroplast ribosome (chloro-ribosome), a dedicated translation machinery responsible for the synthesis of chloroplast genome-encoded proteins, including proteins of the transcription and translation machinery and components of the photosynthetic apparatus. {ECO:0000305|PubMed:10874046, ECO:0000305|PubMed:28007896}.
 
Subunit: Component of the chloroplast large ribosomal subunit (LSU). Mature 70S chloroplast ribosomes of higher plants consist of a small (30S) and a large (50S) subunit. The 30S small subunit contains 1 molecule of ribosomal RNA (16S rRNA) and 24 different proteins. The 50S large subunit contains 3 rRNA molecules (23S, 5S and 4.5S rRNA) and 33 different proteins. {ECO:0000269|PubMed:10874046, ECO:0000269|PubMed:28007896}.
Subcellular location: Plastid, chloroplast {ECO:0000269|PubMed:10874046, ECO:0000269|PubMed:28007896}.
Mass spectrometry: Mass=13553.5; Method=Electrospray; Evidence={ECO:0000269|PubMed:10874046};
Miscellaneous: Two forms of the protein exist; they have the same N- terminal sequence and approximately the same molecular weight. {ECO:0000269|PubMed:8021938}.
Similarity: Belongs to the universal ribosomal protein uL23 family. {ECO:0000305}.
