Regulation summary diagram for rimJ

RimJ is an alanine acetyltransferase that is specific for 30S ribosomal subunit protein S5 [Cumberlidge79, Yoshikawa87]. RimJ also plays a role in maturation of the 30S ribosomal subunit [RoyChaudhuri08, RoyChaudhuri10].

RimJ interacts with pre-30S, but not mature ribosomal subunits [RoyChaudhuri08]. RimJ has overall similarity to RimL [Tanaka89a] and C-terminal similarity to RimI [Yoshikawa87].

Overexpression of RimJ, even when lacking its acetyltransferase activity, suppresses the 16S rRNA maturation defect of an RpsE G28D mutant [RoyChaudhuri08, RoyChaudhuri10]. Overexpression of RimJ decreases the levels of the immature long precursor 16S rRNA (lp16S rRNA) in the RpsE G28D mutant [RoyChaudhuri10]. In a rimJ mutant, the ribosomal protein S5 is not acetylated at the N terminus [Cumberlidge79]. Mutation of the conserved cysteine residues C54 and/or C105 results in loss of RimJ acetyltransferase activity [RoyChaudhuri08].

RimJ acts in transcriptional regulation of the pap pilin operon by environmental conditions in uropathogenic E. coli [WhiteZiegler92, WhiteZiegler02].

Tcp: "thermoregulatory control of pap" [WhiteZiegler90].
