HHsearch alignment for GI: peg_91 and conserved domain: TIGR00010

>TIGR00010 TIGR00010 hydrolase, TatD family; InterPro: IPR015991 Escherichia coli TatD (synonym MttC) has been shown experimentally to be a DNase . On the basis of operon structure, it was originally thought to be involved in the Sec-independent export of protein precursors bearing twin arginine signal peptides by the Tat system . This alternative membrane targeting and translocation system (Mtt), also called twin arginine translocase (Tat) (MttA1A2BC or TatABCD), has been shown to transport fully folded proteins to, or across, the membrane , . However, it was later determined that TatD is not required for this translocation process , . Furthermore, it was noted that no exact correlation exists between the ability of an organism to synthesise a TatD-like protein and whether that organism has a Tat protein transport pathway . Also, with the exception of Escherichia coli , the genetic linkage between TatD and other Tat genes (operon structure) is not maintained. Members of this group may be distantly related to a large 3D fold-based domain superfamily of metalloenzymes . The description of this fold superfamily was based on an analysis of conservation patterns in three dimensions, and the discovery that the same active-site architecture occurs in a large set of enzymes involved primarily in nucleotide metabolism. The group is thought to include urease, dihydroorotase, allantoinase, hydantoinase, AMP-, adenine- and cytosine- deaminases, imidazolonepropionase, aryldialkylphosphatase, chlorohydrolase, formylmethanofuran dehydrogenase, and other enzymes ..
