Ml4 protein from Mesorhizobium loti has a 58% sequence identity with the Ros protein from Agrobacterium tumefaciens that contains a prokaryotic Cys(2)His(2) zinc finger domain. Interestingly, Ml4 is a zinc-lacking protein that does not contain the Cys(2)His(2) motif and is able to bind the Ros DNA target sequence with high affinity. Here we report the H-1, N-15 and C-13 NMR assignments of the Ml4 protein DNA binding domain (residue 52-151), as an important step toward elucidating at a molecular level how this prokaryotic domain can overcome the metal requirement for proper folding and DNA-binding activity.
