Author: gene_x

Abstract: Here are some general statistics about the number of genes in humans, bacteria, and viruses: * Human genes: Humans are estimated to have between 20,000 and 25,000 protein-coding genes. However, the

细菌中被广泛研究的10个基因 (10 Well-Studied Genes in Bacteria)

Author: gene_x

Abstract: 以下是一些在细菌中被广泛研究的基因: * lacZ基因:lacZ基因编码β-半乳糖苷酶,参与乳糖代谢。lacZ基因的研究在细菌基因调控的研究中做出了重要贡献。 * rpoB基因:rpoB基因编码RNA聚合酶的β亚基,是基因表达所必需的。在细菌中,rpoB基因突变与抗生素耐药性有关。 * gyrA基因:gyrA基因编码DNA旋转酶的A亚基,参与DNA复制和修复。在细菌中,gyrA基因突变与抗生

tetR基因在抗生素抗性和细菌生理中的作用 (The Role of the tetR Gene in Antibiotic Resistance and Bacterial Physiology)

Author: gene_x

Abstract: tetR基因是一种细菌基因,编码TetR蛋白,它是一种转录抑制因子。TetR蛋白能够结合到特定的DNA序列,称为Tet运算子,来控制其他基因的表达,包括与抗生素抗性相关的基因。 tetR基因通常存在于质粒中,这是一种与细菌染色体分离的小型环状DNA片段。质粒可以在细菌之间转移,而tetR基因在质粒中的存在可以赋予接收菌株抗生素抗性。这是因为TetR蛋白可以抑制编码抗生素降解酶或转运蛋白的基因表达

The Importance of acrA and acrB Genes in Antibiotic Resistance and Bacterial Physiology

Author: gene_x

Abstract: acrA和acrB基因编码的AcrA和AcrB蛋白质是AcrAB-TolC泵的两个组成部分。AcrA是一种膜融合蛋白,位于AcrB和TolC之间,起到连接的作用。AcrB是一种跨膜效应器蛋白,能够识别各种不同类型的有毒化合物并驱动其从细胞内排出。TolC是一种外膜通道蛋白,负责将底物从细胞内排到细胞外。这三个蛋白质共同组成了AcrAB-TolC泵,使细菌能够有效地排出各种有毒化合物。 除了在细菌

MtlD基因: Exploring the Role of Mannitol-1-Phosphate Dehydrogenase in Microbial Metabolism and Survival

Author: gene_x

Abstract: MtlD refers to a gene that encodes for the enzyme mannitol-1-phosphate dehydrogenase. This enzyme is involved in the metabolism of mannitol, a sugar alcohol that serves as a source of carbon and energ

The p53-R175H Mutation (p53-R175H突变): Implications for Cancer Development and Emerging Therapeutic Strategies

Author: gene_x

Abstract: The p53-R175H mutation refers to a specific change in the TP53 gene, which encodes for the p53 protein. The p53 protein is a crucial tumor suppressor that plays a significant role in preventing the de

Enteroviruses (肠道病毒): Classification, Transmission, and Prevention of a Diverse Group of Viral Infections

Author: gene_x

Abstract: Enteroviruses are a group of viruses that belong to the Picornaviridae family. They are small, single-stranded RNA viruses that can cause a wide range of illnesses in humans and animals. There are ove
