Two segments in bacterial antizyme P22 are essential for binding and enhance degradation of lysine/ornithine decarboxylase in Selenomonas ruminantium.

abstract：:We have developed a general method for determining whether a gene of Escherichia coli is essential for viability. The method requires cloned DNA spanning the gene in question and a reasonably detailed genetic and physical map of the cloned segment. Using this information, one constructs a deletion of the target gene i...
