| Primary Identifier | IPR051476 | Type | Family |
| Short Name | Bac_ResReg_Asp_Phosphatase |
| description | The Rap family proteins are bacterial response regulators with diverse roles in cellular processes such as sporulation and competence development. Members of the family act as aspartate phosphatases, targeting specific response regulators like Spo0F, thereby modulating sporulation initiation. Some Rap proteins also bind to the transcriptional factor ComA, inhibiting its DNA-binding activity and affecting the development of genetic competence. The family is characterized by a conserved domain architecture, including an N-terminal 3-helix bundle domain and a C-terminal TPR domain, which is involved in substrate and inhibitor interactions. Regulatory activity of Rap proteins is often modulated by specific peptide inhibitors, such as Phr peptides, which induce conformational changes that affect their binding and phosphatase activities. |
