  Arthrobacter ramosus S34, which produces trehalose from maltooligosaccharide, was isolated. A trehalose-producing operon, treYZ, was cloned from the genome. Expression experiments with treY and treZ confirmed that they coded malto-oligosyltrehalose synthase and malto-oligosyltrehalose trehalohydrolase, respectively. The amino acid sequence of TreY from A. ramosus S34 and that from Arthrobacter sp. Q36 did not show high identity, nor did those to TreZ.
Key words:trehalose; gene cloning; nucleotide sequence; operon; Arthrobacter
