This entry represents the C-terminal domain of the delta subunit from the clamp-loader complex of Bacillus subtilis and other Gram-positive bacteria, which is structurally similar to that of the DNApol3 delta subunit from E.coli [1-3]. This domain interacts with other subunits in the complex (tau and delta') and the nature of these interactions appear to be hydrophilic in contrast with the one observed in Gram-negative bacteria [3].
