Table 1.

In vitro efficiencies and spin state equilibria of mutants in the turnover of substrate (d-camphor) relative to WT based on comparative substrate/product peak areas in GC analysis of extracts. See Supplementary Material for details.

Mutation	Mutations	Product observed	Turnover efficiency (with respect to WT)	Substrate- bound spin state (390/418 nm), WT at 1.0
3M	V247A-V29SI-V396I	5-exo-hydroxy	39%	0.45
4M	V247G-G248A-V295I-V396I	5-exo-hydroxy	13 %	0.2
2S	F87Y-Y96F	5-exo-hydroxy	60 %	0.51
4M2S	F87Y-Y96F-V247G-G248A-V295I-V396I	5-exo-hydroxy (traces)	<1 %	0.1
