The forkhead-associated (FHA) domain is known as a phosphopeptide recognition domain embedded in regulatory proteins from both eukaryotes and bacteria with various biological functions. In this study, the gene encoding a predicted FHA domain from Mb1858 (residues V24-D155 from the 162 amino acid protein Mb1858) in Mycobacterium bovis was cloned, and U-13C/15N-labeled protein was prepared for backbone and side chain resonance assignments by NMR spectroscopy. These assignments are preliminary work towards the determination of the structure and phosphopeptide-binding properties using NMR methods, which will provide useful information about the function of Mb1858 protein.
