Ordered Locus Names:	MW0879

Organism

Staphylococcus aureus (strain MW2) [Complete proteome] [HAMAP]

Taxonomic identifier

196620 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Staphylococcus

Protein attributes

Sequence length	131 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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. HAMAP MF_01132
Subcellular location	Cytoplasm Probable HAMAP MF_01132.
Sequence similarities	Belongs to the ArsC family. Spx subfamily.
