    Summary
    Acetyl CoA synthase Acs is activated by sirtuin homolog CobB-mediated deacetylation of K609 in Salmonella (Starai, 2002). [More information is available at EcoGene: EG13443]. The CobB protein belongs to the sirtuins, a broadly conserved family of NAD+-dependent protein deacetylases. [More information is available at EcoCyc: G6577].
