Correction for Xin et al., Affinity selection of double-click triazole libraries for rapid discovery of allosteric modulators for GLP-1 receptor

Biochemistry Correction for “Affinity selection of double-click triazole libraries for rapid discovery of allosteric modulators for GLP-1 receptor,” by Ye Xin, Shuo Liu, Yan Liu, Zhen Qian, Hongyue Liu, Bingjie Zhang, Taijie Guo, Garth J. Thompson, Raymond C. Stevens, K. Barry Sharpless, Jiajia Dong, and Wenqing Shui, which published March 9, 2023; 10.1073/pnas.2220767120 (Proc. Natl. Acad. Sci. U.S.A. 120, e2220767120).

The authors note that on page 7, right column, second full paragraph, the line “In addition, the polar group of each PAM (i.e., the heterocycle group of 3-24 and 3-20, and the urea group of 3-29) could form a putative hydrogen bond with K202^2.72b” should instead appear as “In addition, the heterocycle group of 3-24 and 3-20 could form a putative hydrogen bond with K202^2.72b, whereas the urea group of 3-29 is indicated to form hydrogen bonds with E138^1.33b and S206^2.76b.” The online version has been corrected.
