In the original manuscript, the (S)-configuration was mistakenly shown for Cys26 in Figure 1C. The current version of the figure shows the proteinogenic (R)-configuration at this position. All related stereochemical configuration changes have been made in the updated supporting documentation.

更正“Freyrasin 生物合成中形成硫醚的自由基 S-腺苷甲硫氨酸酶的重建和底物特异性”

在原稿中，图 1C 中的 Cys26 错误地显示了 ( S )-配置。该图的当前版本显示了该位置的蛋白质原 ( R )-构型。所有相关的立体化学构型更改都已在更新的支持文档中进行。支持信息可在 https://pubs.acs.org/doi/10.1021/acschembio.1c00536 免费获得。
