Enzymatic properties of CnKBL.

Substrate	WT
	kcat (min−1)a	Km (mM)b	kcat/Km (min−1 mM−1)
L-Thr	0.170 ± 0.39	1.24 ± 0.11	0.14
L-allo-Thr	0.0467 ± 0.0026	0.42 ± 0.086	0.11
DL-3-Hydroxynorvaline	0.0738 ± 0.0043	0.20 ± 0.056	0.37

^ak_cat values of CnKBL were derived from the data shown in Fig. 4b.

^bK_m values represent the Michaelis constant value toward L-Thr.
