Nucleotide binding to the C-terminal nucleotide binding domain of ArsA. Studies with an ATP analogue, 5'-p-fluorosulfonylbenzoyladenosine.


ArsA protein, the catalytic component of the plasmid-encoded anion-translocating ATPase in Escherichia coli, contains two consensus nucleotide binding domains, A1 and A2, that are connected by a flexible linker. ATP has previously been shown to cross-link to the A1 domain upon activation with UV light but not to the A2 domain. The ATP analogue, 5'-p… (More)
