4303bp genomic fragment containing the a mutated version of the dhd coding sequence (replacement of the second cysteine residue in the WCGPCK catalytic motif), along with upstream (1932bp) and downstream (2047bp) regions.
dhdtC34S fails to rescue the female sterility of dhdJ5 homozygotes. dhdtC34S also fails to rescue the male pronucleus chromatin defects observed upon fertilization of eggs laid by dhdJ5 homozygous females.
