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.	Domain

The PRD domain (for PTS Regulation Domain), is the phosphorylatable regulatory domain found in bacterial transcriptional antiterminator such as BglG, SacY and LicT, as well as in activators such as MtlR and LevR. The PRD is phosphorylated on one or two conserved histidine residues. PRD-containing proteins are involved in the regulation of catabolic operons in Gram+ and Gram- bacteria and are often characterised by a short N-terminal effector domain that binds to either RNA (CAT-RBD for antiterminators Pfam:PF03123) or DNA (for activators), and a duplicated PRD module which is phosphorylated by the sugar phosphotransferase system (PTS) in response to the availability of carbon source. The phosphorylations modify the conformation and stability of the dimeric proteins and thereby the RNA- or DNA-binding activity of the effector domain. The structure of the LicT PRD domains has been solved in both the active (pdb:1h99, [2]) and inactive state (pdb:1tlv [4]), revealing massive structural rearrangements upon activation.	Domain
