DEG: a database of essential genes.

abstract：:RNase E is a 472-kDa homo-tetrameric essential endoribonuclease involved in RNA processing and turnover in Escherichia coli. In its N-terminal half (NTH) is the catalytic active site, as also a substrate 5'-sensor pocket that renders enzyme activity maximal on 5'-monophosphorylated RNAs. The protein's non-catalytic C-...
