Proteomic Profiling of the Dioxin-Degrading Bacterium Sphingomonas wittichii RW1

Table 2

Proteins identified as decreased in S. wittichii RW1 during growth on dibenzofuran as compared to acetate. The spots were identified on a minimum of 6 gel images.

Master number^a	Protein accession^b	Gene locus	Protein name	Average ratio^c	𝑡-test^d
821	148551036	Swit_5089	Fumarylacetoacetate hydrolase	−1.99	0.063
470	148553574	Swit_0650	Acyl-CoA dehydrogenase domain	−1.74	0.031
161	148550568	Swit_5129	TonB-dependent receptor	−1.59	0.086

^a Arbitrary identifier for spot location (see Figure 2).
^bNCBI gi∣ number.
^cUsing internal standard as 1.0, >1 is an increase and <1 is a decrease in abundance.
^dStudent’s t-test comparing spot intensity for acetate versus dibenzofuran grown cells.
