| ezrA | hisJ | BL00433 | BL00372 | EzrA; Negative regulator of FtsZ ring formation; modulates the frequency and position of FtsZ ring formation. Inhibits FtsZ ring formation at polar sites. Interacts either with FtsZ or with one of its binding partners to promote depolymerization; Belongs to the EzrA family. | Histidinol phosphate phosphatase; Belongs to the PHP hydrolase family. HisK subfamily. | 0.661 |

| gltA | hisC | BL01971 | BL02769 | Glutamate synthase (large subunit). | Histidinol-phosphate aminotransferase and tyrosine/phenylalanine aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily. | 0.475 |
| gltA | hisD | BL01971 | BL03408 | Glutamate synthase (large subunit). | Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine. | 0.850 |
| gltA | hisF | BL01971 | BL03412 | Glutamate synthase (large subunit). | HisF cyclase-like protein; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit. | 0.643 |
| gltA | hisG | BL01971 | BL03407 | Glutamate synthase (large subunit). | ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Short subfamily. | 0.598 |
| gltA | hisH | BL01971 | BL03410 | Glutamate synthase (large subunit). | Amidotransferase; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate.
