Protocol DOI: Optimizing conditions for the overexpression and purification of membrane proteins for functional and structural studies is usually a laborious and time-consuming process. This process can be accelerated using membrane protein—GFP fusions 1,2,3 , which. Bos taurus, Escherichia coli, Tobacco etch virus.

Superfolder GFP

The study of promoter activities in haloarchaea is carried out exclusively using enzymes as reporters. An alternative reporter is the gene encoding the Green Fluorescent Protein GFP , a simple and fast tool for investigating promoter strengths. However, the GFP variant smRS-GFP, used to analyze protein stabilities in haloarchaea, is not suitable to quantify weak promoter activities, since the fluorescence signal is too low. Using mGFP6 as reporter, we studied six haloarchaeal promoters exhibiting different promoter strengths. The strongest activity was observed with the housekeeping promoters P fdx of the ferredoxin gene and P2 of the ribosomal 16S rRNA gene. Much lower activities were determined for the promoters of the p-vac region driving the expression of gas vesicle protein gvp genes in Halobacterium salinarum PHH1.

We change 15A to G to remove Sap1 restriction site with the silent mutation. This part meets both Biobrick standard and Type2S standard now. The past iGEM only permits Biobrick standard, and the past parts may include Bsa1 restriction site and Sap1 restriction site. In case of Type IIS standard, these sites are illegal. Thus we decided to remove the sites by silent mutation. Changing 15A to G makes no changes in amino acid level. The PCR product was electrophoresed by 1.

The green fluorescent protein GFP is a protein that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. However, GFPs have been found in other organisms including corals , sea anemones , zoanithids , copepods and lancelets. The GFP from A. In cell and molecular biology , the GFP gene is frequently used as a reporter of expression. GFP can be introduced into animals or other species through transgenic techniques , and maintained in their genome and that of their offspring.

Improved GFP Variants to Study Gene Expression in Haloarchaea

Green fluorescent protein GFP was discovered from the jellyfish Aequorea victoria , and several improvements have been carried out to change its physicochemical properties. The resulting improved GFP variants have been used as reporter proteins for bioimaging techniques in various research fields including plant science. Almost all GFP variants were developed using Escherichia coli to improve fluorescence properties in mammalian cells, but the impact in other organisms such as plant cells remains to be determined.

Мозговой штурм был своего рода разведывательным экспериментом, который его создатели называли Симулятором причин и следствий. Сначала он предназначался для использования в ходе избирательных кампаний как способ создания в режиме реального времени моделей данной политической среды. Загруженная громадным количеством информации программа создавала паутину относительных величин - гипотетическую модель взаимодействия политических переменных, включая известных политиков, их штабы, личные взаимоотношения, острые проблемы, мотивации, отягощенные такими факторами, как секс, этническая принадлежность, деньги и власть. Пользователь имел возможность создать любую гипотетическую ситуацию, и Мозговой штурм предсказывал, как эта ситуация повлияет на среду.

Optimization of membrane protein overexpression and purification using GFP fusions

Я пришел, чтобы убедиться, что с вами все в порядке. Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина. Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.

Фреоновые вентиляторы с урчанием наполняли подсобку красным туманом. Прислушавшись к пронзительному звуку генераторов, Сьюзан поняла, что включилось аварийное питание. Сквозь туман она увидела Стратмора, который стоял внизу, на платформе.
