A RECOMBINANT TYPE II RESTRICTION ENDONUCLEASE, NMEAIII, AND A PROCESS FOR PRODUCING THE SAME

摘要

A protein is described that has an amino acid sequence characterized by at least 90% sequence identity with SEQ ID NO: 24, the protein being capable of recognizing a sequence consisting of 5'-GCCGAG-3' within the double-stranded DNA and cleaving the substrate predominantly at 21/19 nucleotides from the recognition site. A method is also described that utilizes the protein for creating a DNA tag for use as a unique identifier for paired end sequencing of DNA or serial analysis of gene expression.
