WebAcetyl-CoA carboxylase (ACC) is a biotin-dependent enzyme (EC 6.4.1.2) that catalyzes the irreversible carboxylation of acetyl-CoA to produce malonyl-CoA through its two catalytic activities, biotin carboxylase (BC) and carboxyltransferase (CT). ACC is a multi-subunit enzyme in most prokaryotes and in the chloroplasts of most plants and algae, whereas it … WebThis biotin maleimide requires mild conjugation conditions. For example, pH of 5.5–8.5 is usually optimal for modifying cysteine residues, and exposure of the reaction solution to air should be minimized whenever possible to avoid the air oxidation of thiol substrates. Most conjugations are done at room temperature. green hell unknown mushroom
