A novel activity in Escherichia coli K-12 that directs restriction of DNA modified at CG dinucleotides.

abstract：:A compound, isolated from the culture fluid of a nadC auxotroph of Escherichia coli grown in a minimal medium, supports the growth of both a nadA and a nadB mutant. This metabolite exhibits an ultraviolet light absorption spectrum and a mass spectrum, different from quinolinic acid. This compound may be the precursor ...
