Comments |
"Acetic acid can be
metabolized to acetyl-CoA either by the PTA-ACKA
pathway or by acetyl-CoA synthetase (ACS) through an
intermediate acetyl-AMP. The high affinity (Km of 200
µM for acetic acid) ACS scavenges acetate at low concentrations
whereas the low affinity PTA-ACKA pathway
(Km of 7-10 mM) is activated in the presence of
high acetate concentrations [primary source]." |
