MICROBIOLOGY Correction for “Unveiling the biosynthetic puzzle of destruxins in Metarhizium species,” by Bing Wang, Qianjin Kang, Yuzhen Lu, Linquan Bai, and Chengshu Wang, which appeared in issue 4, January 24, 2012, of Proc Natl Acad Sci USA (109:1287–1292; first published January 9, 2012; 10.1073/pnas.1115983109).
The authors note that Fig. 2 and its corresponding legend appeared incorrectly. The corrected figure and its corrected legend appear below.
Fig. 2.
Genes involved in dtx biosynthesis in M. robertsii. (A) Schematic map of the dtx biosynthetic gene cluster. (B) Biosynthetic model for hydroxyl and amino acids incorporation and assembly. The dtx B2 instead of dtx B will be synthesized when the amino acid Val but not Ile is selected by the A4 domain. The question mark indicates that the enzyme(s) involved in the reaction have not been determined.
As a result of this correction, the authors note that on page 1288, right column, first full paragraph, lines 6–7, “the first substrate” should instead appear as “the second substrate”; that in the subsequent paragraph, line 2, “the A3 domain” should instead appear as “the A4 domain”; that in the same paragraph, lines 5–6, “A3 (for Val/Ile) and A4 (Val)” should instead appear as “A5 (for Val) and A6 (Ala)”; that on page 1290, right column, first full paragraph, line 10, “the A3 domain” should instead appear as “the A4 domain”; and that in the same paragraph, line 15, “A2 domain” should instead appear as “A3 domain.”
Also as a result of this correction, Fig. S1 appeared incorrectly. Please see separate SI Correction. These errors do not affect the conclusions of the article.
