Database classification	Protein sequence databases
Database description	Database of sequence clusters obtained as a result of all-against-all BLAST search of proteins in 95 organism species.
Features and manner of utilization of database	Gclust is characterized by the capacity to perform classification of homologous proteins with automatically setting the threshold of similarity based on the results of the BLAST search of all proteins of all organism species to be compared. Because a homologous culster can be generated even for proteins with unknown function, Gclust may also be useful to find proteins which play important roles for a particular organisms or taxa of interest through such a generated homologous cluster specific to the organisms or taxa. (phylogenetic profiling).

Background and funding	Name KAKENHI (Grant-in-Aid for Scientific Research) on Priority Areas "Comparative Genomics" from the Ministry of Education, Culture, Sports, Science and Technology of Japan Name Research for the Future Program of the Japanese Society for Promotion of Science Sequence comparison of homologous proteins across many organisms is the very basic of comparative genomics, but pairwise intergenomic comparison has been conventional. Degrees of sequence conservation depend on protein groups;some protein groups are highly conserved, but some orthologs are poorly conserved. Considering these points, we developed a technique which automatically generates ortholog clusters, and applied the technique to functional analysis of protein groups specific to photosynthetic organisms.
