Fig. 8From: Characterization of a cold-active esterase from Serratia sp. and improvement of thermostability by directed evolutionCD spectra of the EstS and 1-D5 in the far-UV spectral region (195–250 nm). CD spectra of Est WT and 1-D5 was more or less similar and an increase in the percentage of β-sheets was reported by CD analysisBack to article page
