T-Coffee alignment of MltA & Sps (A) and EmtA & Rpf (B) proteins. Residues shaded in black are present in 100% of the sequences, dark grey in 80% and light grey in 60%. Bars above the sequences indicate conserved motifs V (partial) & VI from MltA proteins (in Part A) and I, II and III from EmtA proteins (in Part B), as described by Blackburn and Clarke [25]. Putative catalytic residues are marked with an asterisk. Abbreviations are as follows: B. halodurans (BH), B. subtilis (Bsu), Brucella suis (BS), Candidatus Blochmannia floridanus (CBF), C. acetobutylicum (CA), C. perfringens (CP), C. tetani (CT), C. diphtheriae (CD), C. efficiens (CE), C. glutamicum (CG), D. hafniense (DH), E. faecalis (EF), E. coli (EC), E. coli O157:H7 (ECH7), E. coli O6 (ECO6), Haemophilus ducreyi (HD), L. innocua (LI), L. monocytogenes (LM), M. luteus (MLu), M. avium (MA), M. leprae (ML), M. tuberculosis (MT), O. iheyensis (OI), Photorhabdus luminescens (PL), Pseudomonas aeruginosa (PA), Rhizobium loti (RL), Salmonella typhi (Sti), Salmonella typhimurium (ST), Shigella flexneri (SF), S. avermitilis (SA), S. coelicolor (SC) and Yersinia pestis (YP).
