| apaH | sirI | SO_3641 | SO_0481 | Bis(5-nucleosyl)-tetraphosphatase ApaH; Hydrolyzes diadenosine 5',5'''-P1,P4-tetraphosphate to yield ADP; Belongs to the Ap4A hydrolase family. | Cytochrome c maturation system peptidyl-prolyl cis-trans isomerase SirI. | 0.624 |
| bamC | sirI | SO_3580 | SO_0481 | Beta barrel protein translocation lipoprotein component BamC; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. | Cytochrome c maturation system peptidyl-prolyl cis-trans isomerase SirI. | 0.664 |
| infA | sirI | SO_2625 | SO_0481 | Translation initiation factor IF-1 InfA; One of the essential components for the initiation of protein synthesis. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex. | Cytochrome c maturation system peptidyl-prolyl cis-trans isomerase SirI. | 0.586 |
