Gene counti <p>This is the total number of unique genes found in the proteome set, algorithmically computed. For each gene, a single representative protein sequence is chosen from the proteome. Where possible, reviewed (Swiss-Prot) protein sequences are chosen as the representatives.</p> - Download one protein sequence per gene (FASTA)
Proteome IDi <p>The proteome identifier (UPID) is the unique identifier assigned to the set of proteins that constitute the <a href="http://www.uniprot.org/manual/proteomes_manual">proteome</a>. It consists of the characters ‘UP’ followed by 9 digits, is stable across releases and can therefore be used to cite a UniProt proteome.<p><a href='/help/proteome_id' target='_top'>More...</a></p>UP000002590

Prochlorococcus, a fairly recently discovered cyanobacterium (1988), is the smallest known free-living photosynthetic prokaryote. Despite its small size it contributes significantly to global nutrient cycling. It is unique among cyanobacteria in using divinyl chlorophyll a and b as the major light-harvesting pigments, and harvests light with chlorophyll-binding antenna proteins (Pcb proteins) instead of the phycobilisomes used by most cyanobacteria. It is found in low- to mid-latitude oceans and seas, thriving in nutrient-poor waters and at greater depths than its close relative Synechococcus (down to 135m for Prochlorococcus, but only 95m for Synechococcus). Prochlorococcus can be differentiated into low-light (LL) and high-light (HL)-adapted ecotypes that have different physiologies and exist at different depths. Comparison of 12 whole genomes suggests the core genome contains about 1250 genes, while the pan-genome will have more than 5800 genes. This HL-adapted strain was isolated from the Arabian Sea at a depth of 50m in November 1995. Its chlorophyll b/a ratio is 0.34 and it belongs to low chlorophyll b/a clade II, the most abundant clade of Prochlorococcus in the North Atlantic and North Pacific Oceans, often constituting over 90% of the total population; AS9601 strain outgrows MIT 9312 in temperatures exceeding 28 C, and can grow at significantly higher temperatures (31 C) (from research.venterinstitute.org/moore/SingleOrganism.do?speciesTag=AS9601&pageAttr=pageMain).
