“…N-terminal and internal peptide sequences of UDP-sugar pyrophosphorylase, determined by Edman degradation, The peptide sequences were analysed as described in the Materials and methods section. The enzymes and organisms are identified as follows : a, UDPsugar pyrophosphorylase from T. caldophilus GK24 ; b, c, d, UDP-GlcNAc pyrophosphorylase ; e NDP-hexose pyrophosphorylase ; f, g, h, UDP-glucose pyrophosphorylase ; b and i, E. coli [5,36] ; c, Neisseria gonorrhoeae [27] ; d, Bacillus subtilis [28] ; e, Saccharomyces cerevisiae [33] ; f, Mycoplasma pneumoniae [34] ; g, Streptococcus pneumoniae [35] ; h, Xanthomonas campestris [36]. Asterisks indicate identical amino acid residues ; full points represent similar amino acid residues.…”
