An AhpF protein has thioredoxin reductase, peroxidase, and chaperone activities and is derived from Pseudomonas aeruginosa, and a use therefor. By using a novel activity of the AhpF of Pseudomonas aeruginosa according to the present invention, it is possible to produce a plant having strong resistance to various environmental stresses such as oxidative stress or heat stress, thereby making it possible to contribute to increasing crop productivity and mass production of useful constituents. In addition, it is possible to prevent desertification and environmental pollution through the development of transformed plants having resistance to high temperatures and drying.

Modified Saccharomyces cerevisiae yeast that produce terminal alkenes are described. The modification of the Saccharomyces cerevisiae yeast includes insertion of at least one heterologous fatty acid decarboxylase gene, deletion of FAA1 and FAA4, overexpression of HEM3, and triple-deletion of CTT1, CTA1 and CCP1. Methods of producing terminal alkenes by culturing and fermenting the modified Saccharomyces cerevisiae yeast and optionally harvesting the terminal alkenes are also described. Mixtures of terminal alkenes produced by the modified Saccharomyces cerevisiae yeast, and methods of metabolically engineering a yeast for optimizing overexpression of one or more alkenes are also described.
