Two genes involved in the enzymatic conversion of D-alanine to pyruvate are described, alnA and alnR . The alnA gene, located between ara and leu , is probably the structural gene for alaninase. The alnR gene, which can be cotransduced with thr but not with leu , could be demonstrated...
Sequence and properties of wild-type and mutant strains The region located immediately upstream from the Klebsiella aerogenes urease structural genes was sequenced and shown to possess an open reading frame capa... JM Dothie,JR Giglio,CB Moore,... - 《Biochemical Journal》 被引量: 96发表: ...
The data provide new insights into the spatial distribution of many classes of regulatory and structural genes, including those involved in energy metabolism, source-sink relationships, secondary metabolite production, cell wall biology, and cuticle biogenesis. Finally, patterns of similar gene expression...
et al. H3K27me3-mediated silencing of structural genes is required for zebrafish heart regeneration. Development 146, dev178632 (2019). This work shows that Polycomb activity can be pro-regenerative by promoting dedifferentiation through silencing sarcomeric genes in muscle. Article PubMed PubMed ...
The identification of the regulatory or structural genes controlling fruit ripening and senescence is necessary for the improvement of fruit quality. Over the past few years, the abscisic acid (ABA) signalling pathway has been investigated extensively5. For example, as an intracellular messenger, ABA...
Expression of functional B alleles in husk tissue correlates with the coordinate increase in mRNA levels of two structural genes of the pathway, A1 and Bz1, consistent with the postulated role of B as a regulatory gene. 展开 关键词: Zea mays Anthocyanins Restriction Mapping Cloning, Molecular ...
Both wild-type and mutant forms of the methionine regulatory gene, metJ, of Escherichia coli K12 have been cloned in derivatives of pBR322. In cells carrying plasmids with a functional copy of metJ, the methionine regulon appears to be repressed even under conditions of methionine limitation. ...
Northern (RNA) analysis suggested that the activation was, at least partly, at the transcriptional level. In addition, one of these regulatory genes, rinA, was capable of activating L54a int gene transcription. 展开 关键词: Staphylococcus Phages Transcription Factors Viral Proteins Viral Structural ...
With the recognition that most of the human genetic variation contributing to common disease risk lies outside of genes and probably in enhancers, unraveling these mechanisms becomes ever more important. Originally, a popular view was to consider regulatory elements as an entry site for the ...
this leads to marked accumulation of cholesterol in cells and results in the appearance of enlarged, lipid-ladenadrenal glandsseen on MRI orcomputed tomography(CT). Eventually, cholesterol accumulation causes engorgement and results in disruption of the structural and functional integrity of the cell—...
