RPSBLAST alignment for GI: 254780551 and conserved domain: pfam01618

>gnl|CDD|144995 pfam01618, MotA_ExbB, MotA/TolQ/ExbB proton channel family. This family groups together integral membrane proteins that appear to be involved translocation of proteins across a membrane. These proteins are probably proton channels. MotA is an essential component of the flageller motor that uses a proton gradient to generate rotational motion in the flageller. ExbB is part of the TonB-dependent transduction complex. The TonB complex uses the proton gradient across the inner bacterial membrane to transport large molecules across the outer bacterial membrane. Length = 139
