title: Trehalose-producing operon treYZ from Arthrobacter ramosus S34.
abstract: 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 of TreZ.
