This gene is part of a cluster encompassing records UU128-UU138. The products of these genes are responsible for the ATP synthase complex, generation of ATP from ADP and Pi.

The complete list of predicted ATP synthases in U.u. is: UU053, UU054, UU128, UU129, UU130, UU132, UU133, UU134, UU135, UU136, UU137, and UU138.

This gene cluster is a likely candidate for the ATP synthase activity seen in conjunction with the urease present in Ureaplasma urealyticum (see UU427-UU434).

From: Molecular Biology and Pathogenicity of Mycoplasmas, Microbiology and Molecular Biology Reviews, Dec. 1998, p.1118-1119.Shmuel Razin, David Yogev, and Yehudith Naot.

The dependence of ureaplasmas on urea for growth has led to the hypothesis that intracellular urea hydrolysis and the resulting intracellular accumulation of ammonia/ammonium ions is coupled to ATP synthesis through a chemiosmotic type of mechanism. Experimental support for the generation of a transmembrane potential, with resultant ATP synthesis through the ureaplasmal F0F1-type ATPase, first provided by Romano et al. (1986, Medline: 3797330) was more recently extended and confirmed by Smith et al. (1993, Medline: 8501029) [...] It is worth mentioning at this point that the pH of the urogenital tract is usually on the acidic side of neutrality, corresponding to the pH values optimal for ureaplasma growth, maximum increase in delta P, maximum ammonia chemical potential, maximum urease activity, and maximum ATP generation.

Blast Summary:  PSI-Blast Search
A gapped BLAST reveals significant hits to a number of ATP Synthase C Chain proteins. For example: residues 39-109 are 45% similar to ATPL_MYCPN, and residues 38-109 are 50% similar to ATPL_MYCGA. Other significant hits were found against (but were not limited to) the ATP synthase C chains of: A.woodii (1488060), P.modestum (ATPL_PROMO), C.acetobutylicum (1905950) and A.aeolicus (ATPL_AQUAE).

A BLAST against the STDPRO database reveals a significant hit to MG404, described as AtpE, where residues 37-109 are 46% similar to residues 28-100 of MG404. No significant similarity to C.trachomatis or T.pallidum.
