Since these two
residues are invariant in the pMV158 superfamily, the
authors suggest that both residues could be part of the
relaxase active centre, maybe providing part of a coordination
site for Mgþ2 or perhaps being directly involved
in the attack of the scissile phosphodiester bond
at the nic site. It should also be pointed out that a
similarly located acidic residue exists in MOBP relaxases
(see above).

De antemano gracias.
