TABLE 2.
Ambiguously named genes which may be mistaken for homologs to the enterobacterial phoP/phoQ system
| Genus | Genesb | Identity (%)a | Functions | Notes | Key reference |
|---|---|---|---|---|---|
| Saccharopolyspora | phoP/phoR (SACE_6965/SACE_6966)* | 34 | Phosphate and nitrogen metabolism | 240 | |
| Streptomyces | phoP/phoR (SCO4230/SCO4229)* | 33 | Phosphate and nitrogen metabolism, antibiotic synthesis | 49 | |
| Mycobacterium | phoP/phoR | 32 | Virulence, Mg2+ homeostasis, lipid biosymthesis; resistance to some oxidative compounds and antibiotics | Likely homologous to the B. subtilis phoP/phoR (41% identity) | 400 |
| Bacillus | phoP/phoR | 31 | Phosphate metabolism | 415 |
a
Identity is measured at the protein level for the response regulator relatively to S. enterica PhoP.
b
*, While most literature about these genes refers to them as phoP/phoR, these names do not always appear in public databases. Gene names for S. coelicolor A3(2) and S. erythraea NRRL2338 are given.
