Taxonomic identifier

301447 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Lactobacillales › Streptococcaceae › Streptococcus

Protein attributes

Sequence length	134 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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.
Subcellular location	Cytoplasm Probable.
Sequence similarities	Belongs to the arsC family. Spx subfamily.
