This entry represents the N-terminal fragment of the helicase-associated ssDNA binding domain of the conjugative transfer relaxase/helicase TraI [1,2]. This domain adopts a globular structure that closely resembles that of the RecD N-terminal despite little sequence similarity [1,2]. It is part of a larger domain, referred to as vestigial helicase domain, that functions as a ssDNA binding domain [1,2]. This region doesn't have helicase activity or measurable DNA binding affinity itself but it may play a role in either DNA unwinding or regulation of ssDNA transfer from host to recipient cell.
