Any process that initiates the ubiquitin ligase activity of the anaphase-promoting complex. Any process that activates or increases the frequency, rate or extent of ligase activity, the catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate. The process by which one or more ubiquitin moieties are added to a protein. Any process that modulates the frequency, rate or extent of ligase activity, the catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate. Ligase is the systematic name for any enzyme of EC class 6. Any process that activates, maintains or increases the rate of ubiquitin ligase activity that contributes to the mitotic cell cycle. Any process that activates or increases the frequency, rate or extent of the addition of ubiquitin moieties to a protein. Any process that modulates the frequency, rate or extent of ubiquitin ligase activity, the catalysis of the reaction: ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine. Any process that modulates the frequency, rate or extent of the addition of ubiquitin moieties to a protein. Any process that activates, maintains or increases the rate of ubiquitin ligase activity, the catalysis of the reaction: ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine. Any process that activates, maintains or increases the rate of ubiquitin ligase activity during the meiotic cell cycle. Any process that activates or increases the activity of an enzyme. Any process that activates or increases the frequency, rate or extent of the covalent alteration of one or more amino acid residues within a protein.
