Biochemistry. In the article “Structure and function in rhodopsin: Expression of functional mammalian opsin in Saccharomyces cerevisiae” by Ramin Mollaaghababa, Florence F. Davidson, Chris Kaiser, and H. Gobind Khorana, which appeared in number 21, October 15, 1996, of Proc. Natl. Acad. Sci. USA (93, 11482–11486), the following corrections should be noted due to a printer’s error. On page 11484, the sentence “The total amount of rhodopsin recovered in this experiment was 134 mg from about 1.5 × 1010 cells.” should read “… was 134 μg from about 1.5 × 1010 cells.” On page 11486, the sentence “The total amount of chromophore recovered in this study was considerable (134 mg from about 1.5 × 1010 cells) …” should read “… (134 μg from about 1.5 × 1010 cells) …” Also, references 1 through 8 are misnumbered. Reference 1 in the text is reference 2 in the reference list, and so on through reference 8. These corrected references appear below.
