Histidine Biosynthesis [PDF]

open access: yesThe Arabidopsis Book, 2011
Histidine (His) is one of the standard amino acids in proteins, and plays a critical role in plant growth and development. The chemical properties of the imidazole side group allow His to participate in acid-base catalysis, and in the co-ordination of metal ions.

FabR regulates Salmonella biofilm formation via its direct target FabB [PDF]

open access: yes, 2016
Background: Biofilm formation is an important survival strategy of Salmonella in all environments. By mutant screening, we showed a knock-out mutant of fabR, encoding a repressor of unsaturated fatty acid biosynthesis (UFA), to have impaired biofilm ...
