Abstract
A gene encoding a protein constituting sucrose PTS of coryneform bacterium is provided by amplifying a region existing downstream from sucrase gene in coryneform bacterium by the cassette-ligation mediated PCR to obtain DNA encoding sucrose PTS enzyme II, which is a protein defined in the following (A) or (B): (A) a protein which has the amino acid sequence of SEQ ID NO: 2 in Sequence Listing; (B) a protein which has the amino acid sequence of SEQ ID NO: 2 in Sequence Listing including substitution, deletion, insertion, addition or inversion of one or several amino acids, and an activity for binding to sucrose.
Claims5
An isolated protein selected from the group consisting of the amino acid sequence of SEQ ID NO:
- 2 and a variant of the amino acid sequence of SEQ ID NO:
- 2 which has homology of 95% or more to the amino acid sequence of SEQ ID NO:
- 2 and has the activity of sucrose binding enzyme II of the phosphotransferase system from Brevibacterium lactofermentum.
An isolated DNA which encodes a protein comprising the amino acid sequence of SEQ ID NO:
- 2.
An isolated DNA which hybridizes with the nucleotide sequence of the nucleotides 3779 to 5761 of SEQ ID NO:
- 1 under stringent conditions, and which encodes a protein having the activity of sucrose binding enzyme II of the phosphotransferase system from Brevibacterium lactofermentum, wherein the stringent conditions comprise washing at a salt concentration corresponding to 1×SSC, 0.1% SDS, at 60° C.
