Experiment: 2FMG

Carbonic anhydrase activators. Activation of isoforms I, II, IV, VA, VII and XIV with L- and D- phenylalanine and crystallographic analysis of their adducts with isozyme II: sterospecific recognition within the active site of an enzyme and its consequences for the drug design, structure with L-phenylalanine
