Abstract
Genes encoding bacterial oxygen binding proteins are provided. Recombinant expression of at least one of the present bacterial hemoglobin genes increased the growth characteristics and/or carotenoid production levels in microbial host cells grown under microaerobic conditions.
Claims13
An isolated nucleic acid molecule encoding an oxygen binding protein selected from the group consisting of:
- (a) an isolated nucleic acid molecule encoding a polypeptide having an amino acid sequence selected from the group consisting of SEQ ID NO:2, 4, and 6;
- (b) an isolated nucleic acid molecule that hybridizes with (a) under the following hybridization conditions:
- 0.1×SSC, 0.1% SDS, 65° C. and washed with 2×SSC, 0.1% SDS followed by 0.1×SSC, 0.1% SDS, 65° C.;
- (c) an isolated nucleic acid molecule encoding a polypeptide having an amino acid sequence having at least 95% identity to an amino acid sequence selected from the group consisting of SEQ ID NO:
- 2, 4, and 6;
- and
- (d) an isolated nucleic acid molecule that is complementary to (a), (b), or (c).
