Problems solved by technology

Although there have been reports on the extraction of gene fragments, encoded proteins and preparation methods that can induce tumor cell apoptosis from Lentinus edodes C91-3 bacteria, the effects of different gene fragments are not the same, and more expression methods need to be developed urgently. The gene fragment of mushroom C91-3cDNA with strong protein efficacy, good targeting and industrial value

Embodiment Construction

[0038] a. Extract total RNA from the mycelia of Lentinus edodes C91-3 strain:

[0039] Take the mycelium of Lentinus edodes C91-3 strain cultured for 18 days, add liquid nitrogen to the mortar and grind it thoroughly, add 1ml of Trizol and let it stand at room temperature for 30min, after the sample melts, continue to grind until the lysate is transparent, at room temperature After standing still for 5 minutes, centrifuge at 12000 r / min for 5 minutes, transfer the supernatant to another centrifuge tube, then add 0.2 ml chloroform, shake gently, and centrifuge at 4˚C, 12000 r / min for 15 minutes; absorb the upper layer of water Transfer 0.5 ml of phase solution to another clean 1.5ml centrifuge tube, add an equal volume of isopropanol, invert and mix well, let stand at room temperature for 15 min, centrifuge again at 4˚C, 12000 r / min for 10 min, discard the supernatant, Then add 1 ml of 75% ethanol to wash and dry, and finally dissolve the water with DEPC treatment, the total RN...

Abstract

The invention discloses a Latcripin-9 gene segment of a shiitake mushroom C91-3 strain, coding protein, a preparation method and application. A nucleotide sequence of the Latcripin-9 gene segment is shown as SEQ ID NO:1, and a nucleotide sequence of the coding protein is shown as SEQ ID NO:2. The preparation method of the Latcripin-9 gene segment includes following steps: extracting mycelium total RNA of the shiitake mushroom C91-3 strain; performing reverse transcription on the mycelium total RNA to synthesize cDNA; performing PCR amplification on a target gene; taking obtained cDNA as a template, and using a PCR primer with two restriction enzyme cutting sites EcoRI / XhoI for PCR; recycling and purifying a DNA segment.

Description

technical field [0001] The present invention relates to a kind of extract from mushroom C91-3 bacterial strain Latcripin-9 Gene fragment, encoded protein, preparation method and application. The encoded protein has the functions of inducing tumor cell apoptosis, regulating body immunity, regulating cell cycle, anti-tumor, scavenging free radicals and decolorizing dye wastewater. Background technique [0002] Fungi are rich in a variety of bioactive molecules, including ribosome-inactivating proteins, antifungal proteins, lectins, ubiquitin-like proteins, polysaccharides, and kinases. The anti-tumor components are unique in the treatment of tumors with the advantages of less adverse reactions and significant curative effects. Lentinus edodes fungus C91-3 belongs to Basidiomycotina Basidiomycetes Pleurotaceae, which has been preserved in General Microbiology Center of China Committee for Microbial Culture Collection in 2013 with the preservation number CGMCC No.7354. Lentinu...
