然而，在这些已知的生命过程中，一个共同的“规则”似乎从未被打破——所有序列特异性的聚合酶，都必须依赖一条核酸（DNA 或 RNA）作为合成的模板。那么，一个更大胆的问题随之而来——生命世界中是否存在“例外”？有没有一种聚合酶，可以完全摆脱对核酸模板的依赖，直接以蛋白质为模板来合成 DNA？ 换句话说，蛋白质所蕴含的化学信息，能否直接被“翻译”回 DNA ...

Amid the unprecedented challenges presented by the COVID-19 pandemic, a once obscure enzyme found itself in the spotlight: reverse transcriptase. As laboratories worldwide rushed to develop reliable ...

The crystal structure of a human endogenous reverse transcriptase has similarities to HIV reverse transcriptase, a well-known tractable drug target, which will help design drugs to treat cancer and ...

One of the hallmarks of many DNA polymerases is that they proofread as they copy DNA, ensuring high-fidelity duplicates of an organism’s genome. This error-checking ability is missing from enzymes ...

REDWOOD CITY, Calif., Dec. 15, 2021 (GLOBE NEWSWIRE) -- Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company enabling the promise of synthetic biology, today announced the launch of its ...

Alzheimer's disease is the most common cause of dementia and affects more than a tenth of Americans aged 65 and older. The disease has proven difficult to develop new treatments for, and available ...

Viral reverse transcriptase (RT) plays a critical role in replication (e.g., retroviruses, that reverse transcribe RNA templates into complementary DNA) and genome mutations (e.g., ...

Researchers show that polymerase theta can efficiently convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells. Editor's Note: Thomas Jefferson University issued the ...

BRANFORD, CT / ACCESSWIRE / May 28, 2024 / RNAConnect, a pioneering life science tools company, officially announced the commercial launch of UltraMarathonRT™ (uMRT), a next-generation, ...

RNA polymerases are sloppy. A retrovirus with an RNA genome, which is copied into DNA by a reverse transcriptase, is prone to mutations because the enzyme lacks the 3’ to 5’ proofreading capability of ...
