L-Histidine is a natural proteinogenic α amino acid useful as a cell growth supplement that support protein and peptide biosynthesis. L-Histidine is studied in a wide range of applications that involve imidazole chemistry and biochemisty.
L-Histidine is a positively charged imidazole-side chain containing α amino acid. It is metabolized to histamine and is a precursor of the dipeptide carnosine. As one of the 22 proteinogenic amino acids L-His is incorporated into proteins by translation processes in vitro. L-Histidine is an essential amino acid added to cell culture media.

Two-component systems, composed of a histidine kinase (HK) and a response regulator (RR), are the major signal transduction devices in bacteria. Originally it was thought that these two components function as linear, phosphorylation-driven stimulus-response system. Here, we will review how

Histamine or scombrotoxin fish poisoning is caused by ingestion of bacterially produced histamine in fish. Histamine-producing bacteria generally contain the histidine decarboxylase gene (hdc). However, some strains of Photobacterium phosphoreum are known to produce significant levels of histamine, although the
