Involved in solventogenic switch which allows C.acetobutylicum to uptake acid and produce solvents. Acts mainly to detoxify the medium by removing the acetate and butyrate excreted earlier in the fermentation. Source: Recombinant protein corresponding to aa1-221 from Clostridium acetobutylicum Butyrate--acetoacetate CoA-transferase subunit B, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E.coli.
