Cells use proteins to make other proteins - new research could explain how the first proteins arose without other enzymes ...

When a bone grows, our bodies’ proteins help provide the structure. When a muscle tears, proteins help rebuild it. When we fight an infection, transport oxygen in our blood or send messages to a cell, ...

Chemists at University College London have shown how two of biology's most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of ...

A recent study published in the journal Aging sheds light on how aging interferes with the brain’s ability to produce key ...

Scientists discovered chemical reactions that place amino acids on tRNAs and extend peptide chains without enzymes, a key step in the origin of life.

Myristoylation is a co-translational process catalyzed by N-myristoyltransferases (NMTs) on ribosomes, but its mechanism ...
