Abstract
A new inhibitor of insect alpha-amylase, designated RDAI-1, has been purified from rye (Secale cereale L. endosperm RDAI-1 is homologous to wheat homodimeric inhibitors This homology is supported by their similar N-terminal amino-acid sequences, inhibitory activities towards amylases from Tenebrio molitor (Coleoptera) and human saliva, and aggregative properties in gel-filtration chromatography The gene encoding RDAI-1, IdhaR1, is located on the short arm of chromosome 3R, which is moeologous with wheat chromosome arms 3BS and 3DS, where the genes for homodimeric inhibitors have been previously mapped.
