Extended Data Fig. 8: DEPT and HSQC spectrum of the active signaling molecule obtained from Aspergillus sp. ZJ-45.

(a) DEPT (Distortionless Enhancement by Polarization Transfer) shows distinguishable primary carbons, secondary carbons, tertiary carbons and quaternary carbons by comparison with 13C-NMR. (b) C-H correlation deduced from HSQC (Heteronuclear Single Quantum Correlation) is shown in Supplementary Table 2.
