This work underscores the importance of the acquisition of horizontally transferred genes in the evolution of Y. pestis and ... Yersinia genomes had a similar global partition of protein functions, as measured by the distribution of Cluster of Orthologous ... Genome to genome variation in islands with genes encoding functions such as ureases, hydrogeneases and B-12 cofactor metabolite ... although it shares the same core set of approximately 2,500 genes as the other members of the species, whose genomes range in ...

... especially among taxa that belong to recently discovered branches of microbial life. Here, we assemble metagenomes from tongue ... Microbial residents of the human oral cavity have long been a major focus of microbiology due to their influence on host health ... We detected an additional protein with a LysM repeat (COG1388) in 52 out of 55 genomes. While this protein was flanked by genes ... and the NCBI non-redundant protein sequences database to search for protein sequences. For 16S rRNA sequences, we used the 16S ...

Finally, these annotation data were synthesized to produce observations of gene density and number that accord well with ... The index is based on the integration of public transcript, protein, and mapping information, supplemented with computational ... In addition, initial sequence analysis reveals highly ordered chromosomal landscapes associated with paralogous gene clusters ... The creation of a comprehensive gene index requires the synthesis of all available computational and experimental evidence. ...
