5.5.1.4 cloning of gene MIPS encoding the enzyme, DNA sequence determination Zea mays

Protein Variants

EC Number Protein Variants Comment Organism
5.5.1.4 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
