(12) This differs from results obtained with native enzyme, where pterin acts as a sensitizer via efficient singlet-singlet energy transfer to FADH2.
(13) Chemiluminescence appears to result from a side reaction involving singlet oxygen attack on the alpha-methene bridge, yielding a dioxetane.

(20) Evidence is presented for three mechanisms of inhibition by extendible nucleotides (of dhp and ara types) exhibiting frequent internalization: araATP acted as a simple pseudoterminator of alpha and beta polymerases, but was easily extended past singlet sites by Herpesviridae polymerases and only stalled at sites requiring two or more araATP insertions in a row.
