Arthrobacter luteus restriction endonuclease recognition sequence and its cleavage map of SV40 DNA.

The nucleotide sequence at the cleavage site of the restriction endonuclease isolated from Arthrobacter luteus (Alu) has been determined. The endonuclease cleaves at the center of a palindromic tetranucleotide sequence to give even-ended duplex DNA fragments phosphorylated at the 5'-end. The endonuclease cleaves SV40 form I DNA into 32 fragments. The order and sizes of these fragments have been determined to provide an Alu cleavage map of the SV40 genome.
