| degQ | degR | BSU31720 | BSU21940 | Pleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production. | Activation of degradative enzymes (aprE, nprE, sacB) production or activity; Stabilizes the phosphorylated form of DegU, leading to enhanced production of levansucrase, alkaline protease, and neutral protease. | 0.849 |
| degQ | degS | BSU31720 | BSU35500 | Pleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production. | Two-component sensor histidine kinase; Member of the two-component regulatory system DegS/DegU, which plays an important role in the transition growth phase. Involved in the control of expression of different cellular functions, including production of degradative enzymes such as the neutral and alkaline proteases, flagellum formation and biofilm formation. Acts as both a protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to DegU, and a protein phosphatase that dephosphorylates phospho-DegU. | 0.920 |
| degQ | sacB | BSU31720 | BSU34450 | Pleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production. | Levansucrase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. | 0.682 |
| degQ | sacY | BSU31720 | BSU38420 | Pleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production. | Transcriptional antiterminator; In the presence of sucrose, SacY is activated and prevents premature termination of transcription by binding to a RNA- antiterminator (RAT) sequence (partially overlapping with the terminator sequence) located upstream of the sacB gene. Formation of the SacY-RAT complex prevents alternative formation of the terminator, allowing transcription of the sacB gene. In the absence of sucrose, inhibition of SacY activity by SacX leads to termination of transcription; Belongs to the transcriptional antiterminator BglG family. | 0.422 |
