Single-stranded DNA-binding proteins are needed for DNA metabolism, sequestering and protecting transiently formed ssDNA during DNA replication and recombination, detecting DNA damage and recruiting repair proteins. The outer edge of the ssDNA-binding cleft, formed by this domain, has a strongly positive electrostatic surface potential because of the conserved basic residues R49, K54, R65, R80, R86, R90, K97, and R112 [1].

This domain is found ...M regulator protein trans-acting positive regulator (Mga) is a DNA-binding protein that activates the expression of several important virulence genes in group A streptococcus in response to changing environmental conditions [1]. This domain is found in the centre of the Mga proteins. This family also contains a number of bacterial RofA transcriptional regulators that seem to be largely restricted to streptococci. These proteins have been shown to regulate the expression of important bacterial adhesins [2]. This is presumably a DNA-binding domain.
