Activating Compound

Activating Compound Comment Organism Structure
Zn2+ low levels of Zn2+ at 0.00025-0.002 mM result in some activation of AP-B activity up to 25-40% above controls (without Zn2+) Rattus norvegicus

Cloned(Commentary)

Cloned (Comment) Organism
expressed in Escherichia coli Rattus norvegicus

Inhibitors

Inhibitors Comment Organism Structure
Zn2+ Zn2+ inhibits AP-B reversibly at micromolar concentrations (0.005-0.05 mM), AP-B with 0.25 Zn2+ becomes susceptible to degradation by trypsin suggesting that Zn2+ alters enzyme conformation, complete inhibition occurs at 0.050-0.080 mM Rattus norvegicus
