Characterization of a cDNA clone encoding the complete amino acid sequence of cotton isocitrate lyase.
A cDNA clone encoding the glyoxysomal enzyme isocitrate lyase (ICL) (EC 4.1.3.1) was isolated from a library prepared from cotton (Gossypium hirsutum L.) cotyledon poly(A)+ RNA. The clone is 1893 basepairs (bp) in length and contains a 1728 bp open reading frame encoding a polypeptide of 576 residues (Mr = 64,741). The deduced amino acid sequence of cotton ICL is 85.2%, 90.3% and 41.1% identical to ICL from rapeseed, castor bean and E. coli, respectively. Cotton ICL has a C-terminal tripeptide of A-R-M which is a putative trafficking signal for peroxisome (glyoxysome) proteins.
