Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...

Synthetic bacteria with expanded genetic codes can evolve proteins in the laboratory with enhanced properties using mechanisms that might not be possible with nature's 20 amino acid building blocks.

Using quantum chemical methods, a team of researchers led by Dr. Matthias Granold and Professor Bernd Moosmann of the Institute of Pathobiochemistry at Johannes Gutenberg University Mainz solved one ...

Scientists at The Scripps Research Institute (TSRI) report in an upcoming article in the Journal of the American Chemical Society their synthesis of a form of the bacterium Escherichia coli with a ...

DNA and RNA sequencing has become the new watchword for the biological researchers, as this tells them exactly what is going on at cellular level in health and disease. However, it is a partial ...

Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can. With recent innovations ...

Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, ?-actin and ?-actin, are nearly identical, only differing by four amino acids. Yet ...

Each protein or peptide consists of a linear sequence of amino acids. The protein primary structure conventionally begins at the amino-terminal (N) end and continues until the carboxyl-terminal (C) ...

LA JOLLA, CA - In recent years, scientists have engineered bacteria with expanded genetic codes that produce proteins made from a wider range of molecular building blocks, opening up a promising front ...
