Rubber plant translationally controlled tumor protein, encoding gene thereof and application of rubber plant translationally controlled tumor protein

Abstract

The invention discloses a rubber plant translationally controlled tumor protein, an encoding gene thereof and an application of the rubber plant translationally controlled tumor protein. The translationally controlled tumor protein named HbTCTP (Hevea brasiliensis translationally controlled tumor protein) comes from Hevea brasiliensis which belongs to euphorbiaceae rubber category. The translationally controlled tumor protein is a protein (a) or a protein (b). The protein (a) is a protein which is composed of amino acid sequences showed in a second sequence of a sequence table. The protein (b) is a derivative protein, which is provided with antioxidant activity, of the second sequence by using one or more amino acid residues to substitute and / or delete and / or add the amino acid sequences. Experiments show that the rubber plant translationally controlled tumor protein can inhibit active oxygen cutting supercoiled plasmid DNA (deoxyribonucleic acid) generated by a metal catalytic oxidation system, so that the rubber plant translationally controlled tumor protein has antioxidant activity and can eliminate active oxygen in rubber plants.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a rubber tree translation control tumor protein and its coding gene and application. Background technique [0002] Natural rubber, together with steel, petroleum, and coal, is called the four major industrial raw materials. It is a basic industry and an important strategic material related to the national economy and people's livelihood. There are more than 2,000 kinds of rubber-producing plants in the world. Hevea brasiliensis Mull.Arg. has the advantages of high rubber production, good quality, long economic life, convenient rubber mining and low production cost, so it has become the only artificial The most important rubber-producing plants are cultivated, and the natural rubber produced by them accounts for more than 90% of the world's total natural rubber production. [0003] my country is a non-traditional rubber planting area, with limited rubber planting areas and relatively...

AI Technical Summary

Problems solved by technology

Previous studies have shown that the activities of NADH oxidase and cytoplasmic peroxidase on the yellow body membrane of rubber tree are enhanced, while the activities of SOD and CAT are weakened, and the concentration of antioxidants such as ascorbic acid and reduced mercaptans is greatly reduced, resulting in active oxygen and quinones. A large amount of material accumulates, causing the yellow body to rupture and release coagulation factors, which eventually cause the latex to coagulate, block the milk ducts and cause dead skin
