Verbatim
e0“significant differences were observed, especially in the entrance area with altered electronegativity and the presence of a ionic interaction/hydrogen bond network.”
e1“The P1B ATPase heavy metal ATPase 4 (HMA4) is responsible for zinc and cadmium translocation from roots to shoots in Arabidopsis thaliana.”

Other claims from this paper (4)
- Observation HMA4 and its bacterial homolog had broadly conserved zinc pathways, with entrance-region differences.
- Intervention effect Newly identified amino acids lost all or some protein function when mutated.
- Observation HMA4 mutants differed in their zinc translocation ability.
- Observation HMA4 mutants differed in cadmium translocation ability.
