phosphorylated [protein|621357D1FB6AC1B0499732EFE226F982B26CE34E|rsbR] activates the kinase activity of [protein|ADC52A22950736A0435AEEEC43F7407878786A81|rsbT] [Pubmed|23320651]
[wiki|Domains]
RsbRA is composed of an N-terminal nonheme globin domain and a highly conserved C-terminal STAS (Sulphate Transporter and AntiSigma factor antagonist) domain. The C-terminal STAS domain is the target of the serine/threonine-specific kinase [protein|ADC52A22950736A0435AEEEC43F7407878786A81|rsbT] (see below).
