Time scales of flavin photoredox cylces in a Type 1 cryptochrome and a Pyr<>Pyr photolyase^a

	${\tau }_{\mathrm{red}}^{\mathrm{ox}}$	${\tau }_{\mathrm{rec}}^{\mathrm{sq}}$	${\tau }_{\mathrm{de}}^{\mathrm{sq}}$	${\tau }_{\mathrm{red}}^{\mathrm{sq}}$	${\tau }_{\mathrm{rec}}^{\mathrm{hq}}$	${\tau }_{\mathrm{de}}^{\mathrm{hq}}$
Cryptochromeb	1.0	20	140d	~20	-	620d
Photolyasec	0.8	54	-	15	~31	1000

^aAll time scales are in picosecond.

^bTime scales are for insect ApCRY1 and the deactivation dynamics of hydroquinone (hq) is for the mutant C413N of AgCRY1.

^cTime scales are for E. coli CPD photolyase.

^dTime scales of deactivation processes are averages of triple exponential decays, <τ> = ${\sum }_{\mathrm{i}}^3{\mathrm{a}}_{\mathrm{i}}{\tau }_{\mathrm{i}}$.
