Organism

Staphylococcus aureus (strain N315) [Complete proteome] [HAMAP]

Taxonomic identifier

158879 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Staphylococcus

Protein attributes

Sequence length	131 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD. May function to globally reduce transcription of genes involved in growth- and development-promoting processes and to increase transcription of genes involved in thiol homeostasis, during periods of extreme stress By similarity.
Subcellular location	Cytoplasm Probable.
Sequence similarities	Belongs to the arsC family. Spx subfamily.
