Histidine—tRNA ligase
In enzymology, a histidine-tRNA ligase () is an enzyme that catalyzes the chemical reaction ATP + L-histidine + tRNAHis AMP + diphosphate + L-histidyl-tRNAHis This enzyme participates in histidine metabolism and aminoacyl-trna biosynthesis. wikipedia.org

Histidine protonation In histidine structure , full protonation gives a structure with only the double bonded nitrogen having been protonated in the ring and not the single bonded nitrogen. Why is that?
In essence, the histidine imidazole sidecvhain may move around it's protons and electrons when pH is roughly equal to pKa.

PAH gene mutation Analysis of the DNA of the Phenylalanine hydroxylase (PAH) gene in a patient with phenylketonuria revealed a mutation in the protein coding region whose predicted effect would be to replace the amino...
In terms of the way that the question is worded, I imagine the most likely answer would be that the amino acid substitution D > H disrupts the folding of the protein so that it is recognised as being aberrant and is rapidly degraded.

Prevalence of Plasmodium falciparum lacking histidine-rich proteins 2 ...
Findings. A total of 38 articles reporting 55 studies from 32 countries and one territory worldwide were included in the review. We found considerable heterogeneity in the populations studied, methods used and estimated prevalence of P. falciparum parasites with pfhrp2/3 deletions. The derived prevalence of pfhrp2 deletions ranged from 0% to 100%, including focal areas in South America and Africa.
