The 1D ¹³C PREPRINT photo-CIDNP spectra of Trp in an E. coli cell-free system. Dark (i.e., laser-off) and light (i.e., laser-on) NMR data on ¹⁵N-¹³C-Trp (25 μM) are shown in the ¹H (A) aromatic and (B) aliphatic region of a diluted cell-free solution prepared as described in SI Appendix, section 2.5, with data collected and processed as described in SI Appendix, section 2.6.
