Fig. 2From: Identification of a new alanine racemase in Salmonella Enteritidis and its contribution to pathogenesisSpectral change of Alr, DadX and SEN3897 alanine racemases caused by incubation with (a–c) l-alanine and (d–f) d-alanine. The UV–visible spectra (300–500 nm) was obtained at the indicated times. g Expression of alr, dadX and SEN3897 in vitro during their exponential and stationary growth phases through qRT-PCR analysisBack to article page
