Serine/threonine-protein kinase ArnS

Gene

arnS

Organism
Sulfolobus acidocaldarius (strain ATCC 33909 / DSM 639 / JCM 8929 / NBRC 15157 / NCIMB 11770)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Plays an essential role in the controlled expression of archaellum components during starvation-induced motility. May inhibit arnR transcription and promote ArnR translation.1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.1 Publication

Enzyme regulationi

Autophosphorylation is stimulated by Mn2+.1 Publication

Disruption phenotypei

Deletion results in dysregulation of the archaellum regulatory network that leads to reduced motility, though the archaellum is properly assembled. Deletion mutant is still able to sense starvation and to induce archaellum formation, but with a delay at the signal transduction cascade level.1 Publication
