1.15kb insertion of defective (KP) P element in 5' region of Gpdh gene, at nucleotide position 1305, inserted in the same orientation as the Gpdh gene, as for GpdhAT198. This KP element is identical in sequence to the two KP elements isolated by Black et al.,(1987, EMBO J 6:4125--4135 ).
Less than 50% activity of glycerol-3-phosphate dehydrogenase compared to normal-activity wild type allele.
GpdhACyg83/Df(2L)GpdhA flies have reduced Gpdh enzyme activity compared to wild-type. Fast electrophoretic variant.
Isolated from: Cygnet, Tasmania population, 1984.
Isolated from a population in Cygnet, Tasmania, in 1984.
