Amino acids are small chemical substances that combine to produce ... The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan ...

A research team has uncovered a previously unknown type of immune signaling molecule—a novel compound combining histidine and ...

Chemical insight into biological function is the holy grail of structural biology. Small molecules are central players as building blocks, effectors and probes of macromolecular structure and ...

This structure has two helical chains each coiled round the same axis (see diagram). We have made the usual chemical assumptions, namely, that each chain consists of phosphate di-ester groups ...

To create the experimental bird flu vaccine, the researchers added what’s called a histidine tag, or his-tag, to both the H5 and N1. His-tags are short strings of amino acids that have a natural ...
