These lineage specific expansions [55] accounted for almost all of the 7TMR-DISMs in organisms such as, Desulfitobacterium, Leptospira and Cytophaga, which contained multiple copies of these 7TM domains. Accordingly, we named these receptors as 7TMR-HD (for 7TM receptors with intracellular HD domains). Bioinformatics 17:383–384. Furthermore, they were approximately the same size as the prokaryotic rhodopsins and eukaryotic 7TMRs (250–300 residues) and did not deviate in terms of the size distribution of the inter-helix loops from the latter class of proteins. These two proteins could potentially constitute a kinase-phosphoesterase couple that regulates YbeY-DgkA-dependent lipid metabolism.

Agriculture is a field that reaps the benefits of comparative genomics. Makarova KS, Koonin EV (2003) Comparative genomics of Archaea: how much have we learned in six years, and what’s next? We present evidence for considerable variety in the types of uncharacterized surface receptors in bacteria, and reconstruct the evolutionary processes that model their diversity. The N-termini of most 7TMR-DISMs are linked to large extracellular regions that are predicted to assume a globular structure. 10.1101/gr.10.8.1074. This architecture, along with the limited phyletic pattern of these 7TMR (only found in animals), could imply that they were acquired from an as yet unknown prokaryotic source. 10.1126/science.289.5486.1902. 10.1006/jmbi.2000.4315. Vintage, New York, Werner T (2003a) Promoters can contribute to the elucidation of protein function. In terms of domain architecture, the 7TMR-HDs are most similar to the 7TMR-DISMs in possessing a large N-terminal extracellular domain and an intracellular signaling domain. The former category includes the quintessential bacterial two-component-system-modules, namely the histidine kinase and receiver domains, cyclic diguanylate signaling enzymes such as the GGDEF-type cyclase and EAL-type phosphodiesterase domains, cNMP generating cyclases and PP2C phosphatases [3, 22, 39, 40].

The red color shows the distribution of residues on the external surface, which are uniquely conserved in 7TMR-DISMs with 7TMR-DISMED1s. Likewise, contextual information does not provide any evidence for association with cyclic NMP signaling even though HD domains are known to act as phosphodiesterases in this signaling pathway. Interestingly, three DNA binding domains, the AraC-type HTH [44], the OmpR-type HTH [45, 46] and the bacterial IS1-like Zn finger domains (VA & LA unpublished), are also fused C-termini of certain 7TM receptors from Leptospira and Cytophaga (Figure 2).

Sequence profile searches with the extracellular domain did not establish any relationship with previously known globular domains. They transduce downstream signals via various intracellular pathways and are likely to play an important regulatory role in several pathogenic and free-living bacteria. Comparing the genomes of different organisms allows us to understand what distinguishes each species, its adaptation to the environment, and even its interaction with other organisms. 10.1006/jmbi.1993.1413. Felsenstein J: PHYLIP – Phylogeny Inference Package (Version 3.2). The membrane-spanning domain of the 5TMR-LYT family is distinguished from other membrane spanning domains by the presence of certain distinctive sequence features. A small number of proteins in either group lacked a distinct extracellular globular domain, suggesting secondary loss of these domains. Bioinformatics 19:780–781, Clark AG(1990) Inference of haplotypes from PCR-amplified samples of diploid populations.

Application of COG • The most straightforward application of the COGs is for the prediction of functions of individual proteins or … An examination of the domain architectures of these 7TM proteins reveals considerable diversity around a shared basic architectural blue print. The most significant application of comparative genomics in molecular medicine is the identification of drug targets of many infectious diseases. Nature 423:241–254, Kent WJ (2002) BLAT—the BLAST-like alignment tool. Hence, it is possible that these receptors could act through a similar mechanism in which the signal is relayed via an interplay between the extracellular ligand-binding domain and the 7TM domain. The PhoH-YbeY-diacylglycerol kinase gene neighborhood [58] is defined by several conserved genes (Figure 8A), which often occur adjacent to each other or the gene for the well-studied bacterial membrane-associated enzyme diacylglycerol kinase (DgkA) [59, 60]. 1999, 286: 707-711.

Kraulis PJ: Molscript. These repeats may act as structural scaffolds that link the 7TMR-DISMs to intracellular protein complexes. Multiple sequence alignment was constructed as detailed in the legend to Figure 1. The sequence alignment also suggests that the 7TMR-DISMED1s are likely to preserve the spacious cavity of these jellyrolls with a characteristic triangular outline (Figure 3A). 10.1126/science.289.5480.739. This alignment was then provided as input to the SWISS-MODEL server [75] to generate a homology model using the PROMODII program. Notredame C, Higgins DG, Heringa J: T-Coffee: A novel method for fast and accurate multiple sequence alignment. Furthermore, some diversity was observed in the intracellular domains associated with the 7TM domains from the proteins belonging to these lineage specific clusters (Figure 2). We specifically concentrated on those regions that formed distinct clusters with multiple representatives from the same or different organisms because they were likely to represent evolutionarily conserved domains with functional relevance in a wide range of organisms.
