Arthrobacter luteus (ALU) is a species of gram-positive bacteria in the genus Arthrobacter. A. luteus is facultatively anaerobic, pleomorphic, branching, non-motile, non-sporulating, non-acid-fast, catalase-positive and rod-shaped (0.6-1.0 x 0.8-10.0 μm x μm).^[1] All members of the Arthrobacter genus are obligate aerobes.^{[contradictory]}

A restriction endonuclease enzyme is extracted from the bacterium and acts at the centre of a palindromic tetranucleotide sequence to give even-ended duplex DNA fragments phosphorylated at the 5'-end. The restriction site Alu-I itself is a 4-base cutter: AG/CT.^[2] The Alu retrotransposon is named after the bacterium's abbreviation. The bacterium is also used to produce zymolyase,^[3] which can degrade yeast cell wall.

A endonuclease restriction that occurs from Arthrobacter luteus has been isolated and the nucleotide sequence at the cleave site of the restriction isolated. The cleaveage occurs at the center of the palindromic tetranucleotide sequence, which gives even-ended duplex DNA fragments phosphorylated at the 5’-end.^[4]
