Analyses of CycA amino acid sequences.

Abstract

<p>(<b>A</b>) Partial CycA amino acid sequence alignment of various mycobacteria (the conserved G122 residue is indicated by the arrow). (<b>B</b>) 2-dimensional topological representation of <i>M. bovis</i> CycA with the G122S mutation found in all BCG (circled) in the extracellular loop (boxed) between the 3^rd and 4^th trans-membrane helices from the amino (N) terminus.</p
