-finger domain 'B' does not recognize the target subsite. In this case, the reporter gene is not activated; thus the yeast does not grow on a medium lacking histidine and forms a white colony on a medium containing X-gal (see Fig. 1B ). AD

with solvent. Most proteins fold into globular domains, which have a minimal surface area. Peptides from 10 to 30 kDa typically fold into a single domain. Peptides larger than 50 kDa typically form two or more domains that are independently folded
