Application

DL-Histidine has been used to study the fouling behaviour of polyethersulfone ultrafiltration membranes made with different PVP (polyvinylpyrrolidone).
DL-Histidine is the mixed isomer of D- and L-histidine. DL-Histidine may be used to evaluate the efficiency of amino acid chiral ligand exchange media and systems and in running buffers for capillary electrophoresis.

Biochem/physiol Actions

L-Histidine is involved in the one-carbon unit metabolism. It is associated with protein methylation. L-Histidine is a part of hemoglobin structure and function. L-Histidine is a component of dipeptides with antioxidative property. Histidine serves as a precursor for the formation of histamine, which is associated with allergic responses. Urocanic acid, an immune response modulator in skin is also biosynthesised from histidine.

WRKY transcription factors and mitogen-activated protein kinase (MAPK) cascades have been shown to play pivotal roles in the regulation of plant defense responses. We previously reported that OsWRKY53-overexpressing rice plants showed enhanced resistance to the rice blast fungus. In this

The cadherins Fat and Dachsous regulate cell polarity and proliferation via their heterophilic interactions at intercellular junctions. Their ectodomains are unusually large because of repetitive extracellular cadherin (EC) domains, which raises the question of how they fit in regular intercellular

Thermosensitive genic male-sterile (TGMS) lines, which are male-sterile at restrictive (high) temperatures but male-fertile at permissive (low) temperatures, have been widely used in breeding two-line hybrid rice (Oryza sativa L.). Here we find that mutation of thermosensitive genic male sterile

Septins are guanosine-5'-triphosphate-binding proteins involved in wide-ranging cellular processes including cytokinesis, vesicle trafficking, membrane remodelling and scaffolds, and with diverse binding partners. Precise roles for these structural proteins in most processes often remain elusive. Identification of small molecules that inhibit
