Disruption of guanosine catabolism-related genes. (a) The related pathways of guanosine catabolism in E. coli. (b) Production of guanosine by deleting guanosine catabolism-related genes. All data represent the mean ± s.d. (n = 4 biologically independent samples). Error bars were analysed by Student’s t test (two-sample, two-tailed; *** p value < 0.001)
