CC   -!- FUNCTION: Might play a role in cell growth during glycolysis.
CC       {ECO:0000305|PubMed:24025676}.
CC   -!- DISRUPTION PHENOTYPE: Produces less H(2) during fermentation on minimal
CC       glucose medium, but not on complex glucose or complex formate medium.
CC       Alters production of organic acids when grown on minimal glucose
CC       medium; complementation was not reported.
CC       {ECO:0000269|PubMed:24025676}.
CC   -!- MISCELLANEOUS: Encoded by the cryptic lambdoid prophage DLP12.
CC   -!- MISCELLANEOUS: Missing about 60 C-terminal residues compared to
CC       orthologs. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the tfa family. {ECO:0000305}.
