Fig. (1). Comparison of the amino acid sequences of NATs from mycobacteria.

A schematic diagram to show the amino acids which differ between MMNAT and TBNAT based on a ClustalW alignment (http://www.ebi.ac.uk/clustalw) and Espript [63]. The amino acids indicated above the bar are TBNAT residues and the amino acids indicated below the bar are MMNAT residues. White lines indicate residues which are a conserved substitution, grey lines indicate residues which are semi-conserved, black lines indicate residues which are nonconservative and the dashes indicate deletions since MMNAT is shorter than TBNAT. The numbering is based on the TBNAT sequence. Amino acids are indicated by single letters.
