    6.4.1.3 | ATP + acetyl-CoA + HCO3- |
n-butyryl-CoA (0.5 mM) is carboxylated at 4.6% compared to carboxylation of acetyl-CoA or propionyl-CoA |

the bifunctional enzyme also catalyzes the carboxylation of acetyl-CoA. Vmax/Km for carboxylation of propanoyl-CoA is 1.6fold higher than Vmax/Km for carboxylation of acetyl-CoA. Quite specific for ATP. No activity with ADP, AMP, GTP, CTP, UTP, or dTTP (0.2 mM) |
