Sequence alignment of N. gonorrhoeae PatA and related hypothetical proteins found in the genome databases with family 1 O -acetyltransferases. The family of proteins presented in the upper block of sequences includes AlgI from both P. aeruginosa PAO1 and Azotobacter vinelandii, a transporter of acetate involved in the O-acetylation of the exopolysaccharide alginate [6]. The residues in bold face and yellow highlight denote greater than 50% and 80% identity, respectively, within the separate blocks of sequences. The asterisks identify conservation between the two blocks of sequences while the residues in red are invariant amongst all sequences. Abbreviations (accession numbers): Pa, P. aeruginosa (U50202); Av, Azotobacter vinelandii, (AF027499); Hp, Helicobacter pylori (AE000596); Tp, Treponema pallidum (AE001232); Lc, Lactobacillus casei, (P35855); Sa, Staphylococcus aureus (D86240); Sm, Streptococcus mutans (AF049357); Bs, Bacillus subtilis (P39580), Ng, N. gonorrhoeae (AAW89272); Nm, N. meningitidis (NP284200); Cv, Chromobacterium violaceum (NP903736); Pl, Photorhabdus luminescens (NP927855); Hh, Helicobacter hepaticus (NP860615); Cj, Campylobacter jejuni, (NP281794); Cc, Campylobacter coli (ZP00366780); Zm, Zymomonas mobilis (YP162181); Bj, Bradyrhizobium japonicum (NP767015); Gv, Gloeobacter violaceus (NP923893); Ba, Bacillus anthracis (NP843401); Bc, B. cereus (NP977299); Pg, Porphyromonas gingivalis (NP905383); Bt, Bacteroides thetaiotaomicron (NP811593); Bf, Bacteroides. fragilis (YP101412).
