N-Terminal Amino Acid Sequences of Intact and Cleaved Forms of Mung Bean Nuclease

Abstract

We report, for the first time, the N-terminal amino acid sequences of both intact and cleaved forms (fragments A and B) of Mung bean nuclease, purified from sprouts of Vigna radiata or purchased from Amersham Biosciences. The N-terminal sequence of Mung bean nuclease shows high similarity with the putative bifunctional nuclease from Arabidopsis thaliana (AC: AAM63596).

Abbreviations

MBN:Mung bean nuclease

PAGE:polyacrylamide gel electrophoresis

PVDF:poly(vinylidene difluoride)

SDS:sodium dodecyl sulfate

Key words

Mung bean nuclease - Vigna radiata - Fabaceae - ribosome-inactivating protein - Edman degradation
