Product distribution during degradation of RDX by purified XenA and XenB enzymes (average of duplicate assays) and by whole cells of P. putida II-B and P. fluorescens I-C (single replicates)

Assay	RDX (μmol)		Products (μmol)				Mass balance (%)
	Initial	Residual	MNX	MEDINA	NDAB	HCHO	C	N
P fluorescens I-C	21.5	15.0	0.0	1.4	0.0	13.2	92	74
P putida II-B	21.5	11.7	0.0	0.4	0.3	2.7	60	56
XenB	69.1	29.2	0.0	37.4	0.0	82.2	100	78
XenA	69.1	28.9	0.2	23.5	1.5	76.1	98	66

Samples were collected for analysis after about half the initial RDX had been degraded (corresponding to approximately 100 and 400 h for whole cell assays with P. fluorescens I-C and P. putida II-B, respectively, and 4 and 24 h for XenB and XenA, respectively)
