Application

Application Comment Organism
biotechnology the enzyme is a possible target for genetic modification of maize plants to get low phytic acid containing variants Zea mays

Cloned(Commentary)

Cloned (Comment) Organism
cloning of gene MIPS encoding the enzyme, DNA sequence determination Zea mays

Protein Variants

Protein Variants Comment Organism
additional information maize mutant ipa 1-1 produces kernels containing low phytic acid, reducd by 66% compared to the wild-type maize kernels probably due to a mutation in the gene encoding the enzyme, i.e. gene MIPS, overview Zea mays
