Polymorphic bio-enzyme preparation for improving dark tea quality and tea making process
PendingCN119632114AImprove thermal stabilitygood storage stabilityPre-extraction tea treatmentAmylasePectinase
The invention relates to the technical field of tea making, and discloses a polymorphic bio-enzyme preparation for improving dark green tea quality and a tea making process, the polymorphic bio-enzyme preparation contains tannase, polysaccharide hydrolase, polyphenol oxidase, protease and the like, the polysaccharide hydrolase comprises cellulase, pectinase, beta-glycosidase or amylase, and the polyphenol oxidase comprises cellulase, pectinase, beta-glycosidase or amylase. The enzyme is subjected to crosslinking-embedding-crosslinking immobilization treatment, is compounded with bacillus natto fermentation liquor and high-temperature aroma-enhancing yeast fermentation liquor, and is applied to a dark tea making process, so that the thermal stability and storage stability of the enzyme are improved, and the enzyme activity is improved; the content of aroma substances such as beta-linalool, geranyl acetone and dihydroactinidiolide can be increased in the fermentation process, so that the problem of bitterness of the dark green tea is solved, the quality of the dark green tea is greatly improved, and the method has very good popularization and application values; the process is simple, easy to operate and suitable for large-scale production and use.

Use of the vvihat5 gene in plant breeding
PendingCN122278928ADifferent associativityDifferent functionsBiotechnologyTranscriptional regulation
This invention provides VviHAT5 The application of genes in plant breeding belongs to the field of plant breeding technology, and is the application of genes in plant breeding. VviHAT5 Gene overexpression in plants: When the plant is Arabidopsis thaliana, overexpression... VviHAT5 Genes were used to obtain salt-sensitive Arabidopsis thaliana varieties; when the plants were grapevines, overexpression was performed. VviHAT5 Genes were used to obtain salt-tolerant grape varieties. This invention verifies... VviHAT5 for HCT1;1 The upstream transcriptional regulators, and confirmed VviHAT5 It can be controlled HCT1;1 Expression, in turn, affects the plant's Na+. + / K + Balance and salt stress response can be achieved through overexpression VviHAT5 Genes are used to breed salt-tolerant grape varieties or salt-sensitive Arabidopsis varieties for scientific research.

Ubiquitin probe for targeting deubiquitinating enzyme hyposulfonic acid as well as preparation method and application of ubiquitin probe
PendingCN121873188ASimple structuredifferent functionsDepsipeptidesBiological testingDeubiquitinating enzymeDrug target
The invention discloses a ubiquitin probe targeting deubiquitination enzyme hyposulfonic acid and a preparation method and application thereof, the structural general formula of the ubiquitin probe is Biotin-Ub-W, Ub is a ubiquitin molecule; w is a nucleophilic warhead group, can be specifically subjected to a covalent reaction with a hyposulfonic acid (-SOH) functional group formed by cysteine at an active site of DUBs under oxidative stress, and has no reactivity on reduced cysteine (-SH). The method can be used for specifically marking, enriching and identifying the DUBs regulated and controlled by redox in a cell or tissue sample, provides an unprecedented tool for researching the functions of the DUBs in related diseases such as cancers and neurodegenerative diseases, and can be used for screening drugs targeting the specific state.
