Buscoi <p>The Benchmarking Universal Single-Copy Ortholog (BUSCO) assessment tool is used, for eukaryotic and bacterial proteomes, to provide quantitative measures of UniProt proteome data completeness in terms of expected gene content. BUSCO scores include percentages of complete (C) single-copy (S) genes, complete (C) duplicated (D) genes, fragmented (F) and missing (F) genes, as well as the total number of orthologous clusters (n) used in the BUSCO assessment.</p> C:96.2%[S:95.9%,D:0.3%],F:0.9%,M:2.9%,n:788 synechococcales_odb10
Completenessi <p>Complete Proteome Detector (CPD) is an algorithm which employs statistical evaluation of the completeness and quality of proteomes in UniProt, by looking at the sizes of taxonomically close proteomes.

Model cyanobacterium that carries a complete set of genes for oxygenic photosynthesis, Synechocystis is also studied for its stress response and metabolism. The first glucose-tolerant strain was sequenced in 1996 (this strain Kazusa, SYNY3),while a second glucose tolerant strain, Synechocystis GT-S, and has been maintained as frozen glycerol stocks since the late 1980s. Careful comparison reveals that there is a single nucleotide change and two IS insertions between the Kazusa strain and the GT-S strain, with some changes to the sequence of the Kazusa strain also noticed. Although they have not been resubmitted strain GT-S also encodes the 4 plasmids sound in SYNY3 (adapted from PMID 21803841).
