High impact information on dcuS

Phospho-NarL protein protected operator sites in the aspA and dcuS promoter regions from DNase I cleavage in vitro [1].
A plasmid carrying the dcuSR operon restored the C4-dicarboxylate inducibility of dcuB expression in the dcuS mutant to levels exceeding those of the dcuS+ strain by approximately 1.8-fold [2].
The dcuS mutation affected the expression of other genes with roles in C4-dicarboxylate transport or metabolism [2].
Surprisingly, anaerobic fumarate respiratory growth of the dcuS mutant was normal [2].
