Abstract

17 beta-Estradiol dehydrogenase (EC 1.1.1.62) catalyzes the interconversion of estradiol and estrone in human term placenta. We have raised a specific polyclonal antibody to this abundant placental enzyme to study its role in late pregnancy events and its molecular biologic characteristics. In this work the 17 beta-estradiol dehydrogenase antibody was used to isolate and sequence a complementary deoxyribonucleic acid clone encoding about 98% of the amino acid sequence of the 17 beta-estradiol dehydrogenase molecule. This sequence verifies previous sequence data on the molecule's steroid binding site and also localizes a putative nicotinamide adenine dinucleotide binding region similar to that of many other pyridine nucleotide-dependent dehydrogenases. Isolation of the complementary deoxyribonucleic acid for 17 beta-estradiol dehydrogenase expands our knowledge of the structure-function relationships of the enzyme and is a major step in our understanding of its biologic function in pregnancy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
