Cold-shock regulatory elements, constructs thereof, and method of use
View Patent ↗Regulatory elements of the 5′UTR of cold-shock inducible genes that prolong the expression of cold-shock inducible genes under conditions that elicit the cold-shock response in a bacterium, repress the expression of the cold-shock inducible genes under physiological conditions, or enhance the translation of cold-shock inducible genes under conditions that elicit a cold-shock response in bacteria; vectors incorporating these elements; and methods for expressing proteins.
1. An isolated nucleic acid molecule that regulates the expression of a cold shock inducible gene under conditions that elicit a cold-shock response in a bacterium, wherein said isolated nucleic acid molecule consists of nucleotides 1-11 of SEQ. ID NO:55, nucleotides 56-117 of SEQ. ID NO:55, nucleotides 123-135 of SEQ. ID NO:55, SEQ. ID NO:49, or SEQ. ID NO:50.
2. The nucleic acid molecule of claim 1 consisting of nucleotides +1 to +11 of the cspA 5′-UTR (nucleotides 1 to 11 of SEQ. ID. NO. 55).
3. The isolated nucleic acid molecule of claim 1 , which interacts with CspA protein.
4. The nucleic acid molecule of claim 1 consisting of nucleotides +56 to +117 of the cspA 5′-UTR (nucleotides 56 to 117 of SEQ. ID. No. 55).
5. The nucleic acid molecule of claim 1 consisting of nucleotides +123 to +135 of the cspA 5′-UTR (nucleotides 123 to 135 of SEQ. ID. NO. 55).
6. The nucleic acid molecule of claim 1 consisting of a sequence selected from the group consisting of SEQ ID NO:49 and SEQ ID NO:50.
