PF13675 | Type IV pili methyl-accepting chemotaxis transducer N-term (PilJ) | Type IV pili methyl-accepting chemotaxis transducer N-term | This domain is found on many type IV pili methyl-accepting chemotaxis transducer proteins [1] where there is also a HAMP signature towards the C-terminus. It is a monomodular four-helix bundle and recognises nitrate and nitrite (Matilla et al. FEMS ... | Domain |
