a luxI homologous AHL synthetase from Sinorhizobium meliloti 1021

The S. meliloti strain Rm1021 harbors at least two quorum-sensing systems; one of them is sinR/sinI system, The sinI is responsible for the production of several novel AHLs, including C12-HSL, 3-Oxo-C14-HSL, C16:1-HSL, 3-Oxo-C16:1-HSL, C18-HSL, some of theses are the longest AHLs identified so far. The sin system correlates with a delay in the appearance of nitrogen-fixing nodules, as well as with an overall decrease in the number of pink nodules, suggesting a role for quorum sensing in establishing a successful symbiosis with Medicago sativa.

As a autoinducer synthatase, the use of sinI is the same with luxI, namely to produce AHLS.
