General description
L-Histidine is a hydrophilic essential amino acid that has a basic sidechain containing an imidazole group.
Biochem/physiol Actions
L-Histidine is biosynthesized from ATP, 5-phosphoribosyl-1-pyrophosphate (PRPP), and glutamine. This essential amino acid can be degraded to glutamate by histidiase, urocanase and imidazolonepropionase; it is also the precursor of histamine by action of histidine decarboxylase.

Protein aggregation can affect the quality of protein-based therapeutics. Attempting to unravel factors influencing protein aggregation involves systematic studies. These studies often include sodium azide or similar preservatives in the aggregation buffer. This work shows effects of azide on aggregation

Elucidating how a population of non-growing bacteria generates mutations improves our understanding of phenomena like antibiotic resistance, bacterial pathogenesis, genetic diversity and evolution. To evaluate mutations that occur in nutritionally stressed non-growing bacteria, we have employed the strain B. subtilis
