Bioinformatic analysis of sensory domains of GdpXs, EdpXs, GEdpXs and HGdpXs in Xanthomonas oryzae pv. Oryzae.
| Sensory domain | Possible function | Protein |
|---|---|---|
| REC | Forming part of response regulator of a TCS, modulating c-di-GMP levels in response to intra- or extra-cellular signals received by their cognate histidine kinase sensor. | GdpX4, GEdpX3, GEdpX6, GEdpX9, EdpX2, HGdpX1, HGdpX2 |
| PAS(C) | Perceiving changes of oxygen, light, redox potential, small ligands, and overall energy levels of a cell | GdpX10, GEdpX1, GEdpX3, GEdpX7, GEdpX10 |
| GAF | Regulating c-di-GMP catalytic activity by cGMP binding | GdpX5, GdpX10, GEdpX1, GEdpX4 |
| HAMP | Regulating phosphorylation or methylation of homodimeric receptors by ligand binding | GdpX11, GEdpX2, GEdpX8 |
| Cache_1 | Involved in small-molecule recognition of various chemotaxis receptors | GdpX6 |
| CHASE3 | Containing an extracellular sensory domain is hypothesized to recognize unknown environmental signals | GdpX5 |
| Reg_prop- and Y_Y_Y | Forming part of the periplasmic sensor domains with unknown function | GdpX2, GdpX3 |
| MHYT | Comprised of an N-terminal triplet tandem repeat, and each repeat contained two transmembrane helices | GEdpX5 |
| DUF3391 | Not characterized yet for its function | HGdpX3 |
