Chemical compound.
1
The amino acid l-histidine is a natural component of plants and animals.
2
L-histidine is included because low levels can contribute to low sex drive.
3
We are exploring the inhibition of histidine kinases, constituents of two-component systems.
4
Serum histidine in both groups reached levels similar to those of histidinemic patients.
5
The latter group of toxins presents an additional histidine that appears important for catalysis.
6
Directed mutagenesis of the protein reveals two highly conserved histidine residues required for function.
7
Enzyme inactivation with diethylpyrocarbonate indicated that a single histidine residue was involved in catalysis.
8
The structures of GpgP reported here are the first crystal structures for histidine-phosphatase-type GpgPs.
9
Of these compounds, nine inhibited the catalytic activity of two or more histidine kinases.
10
Histamine is synthesized in monocytes and T cells by the induction of histidine decarboxylase.
11
A histidine tag present at the N-terminus allowed for easy purification of the recombinant protein.
12
The additive is considered an efficacious source of the amino acid l-histidine for fish species.
13
We also found that the solvent accessibility of histidine-containing M2 is greater than without histidine.
14
The aminotransferase activity of the enzyme towards phenylalanine was inhibited by the addition of histidine.
15
Spin coupling to the nitrogen of a coordinated histidine imidazole was observed for both metals.
16
Therefore the role of histidine residues in the function of hOAT4 was examined by site-directed mutagenesis.
