Figure 1.
Sequence alignment of hNEH1 and hNEH2 with E. coli MutM/Nei. Identical residues are underlined. Box A contains catalytic N-terminal Pro; box B, helix-2-turn-helix motif; box C, Zn-finger motif. Potential nuclear localization signal (NLS; by psort) in NEH1 is underlined. N-terminal Met is cleaved after synthesis.
