Two uncharacterized FtsX-like proteins, (1220 aas [A0ECD8] and 1209 aas [A0ECD9], respectively; both with 10 TMS in a 1+3 + 2 + 1 +3 TMS arrangement; 2-4 are homologous to 8-10; the FtsX domain; P. tetraurelia has at least 5 paralogues.) Three ATPases appear to most closely resemble the ABC3 ATPase of 3.A.1.207.7; two of these are very similar (95% identity), having the same size (295 aas) (A0BKU3 and A0E2Z0) while the third is larger (350 aas) (A0CMB8) and shows only 45% identity with the other two. We suggest the first two very similar proteins function with the two FtsX-like proteins while the third (A0CMB8) serves an idependent function. However, this has not been established.
