Abstract
The title of the 5 June report on page 1445 by R. C. deL. Milton et al. should have been "Total chemical synthesis of a D-enzyme: The enantiomers of HIV-1 protease show reciprocal chiral substrate specificity." Figure 3 in the same report (p. 1447) was inadvertently printed upside down. The labels "L-HIV protease" and "D-HIV protease" were therefore under the wrong illustrations. The correct figure is printed below.
