Characterization of two novel proteins containing the rhodanese homology domain: YgaP and YbbB of Escherichia coli Abstract Rhodanese homology domains are ubiquitous structural modules found in eubacteria, eukaryotes and archaea. The rhodanese homology domain may comprise the entire structure of a protein. Alternatively it is found as tandemly repeated modules in which the C-terminal domain displays the properly structured active site. Finally it is found as a member of many multidomain proteins. Although some members of this family of proteins show sulfurtransferase activity in vitro, their specific physiological functions remain largely undefined. Fusion of a rhodanese domain to different protein domains of known or unknown functions provides important clues to the diverse roles for these proteins

The Internet has a loosely hierarchical structure. At the top of the hierarchy are the backbones, also called Internet Access Providers (hereafter IAPs). The second layer of the hierarchy is comprised of Internet Service Providers (hereafter ISPs). At the bottom of the hierarchy are the end users, consumers, who browse the web, and websites. To provide access to the whole Internet, the providers must interconnect with each other and share their network infrastructure. Two main forms of interconnection have emerged – peering under which the providers carry each other’s traffic without any payments and transit under which the downstream provider pays the upstream provider a certain settlement payment for carrying its traffic.
