S. Kleff et al., NUCLEOTIDE AND DEDUCED AMINO-ACID-SEQUENCE OF A PUTATIVE HIGHER MOLECULAR-WEIGHT PRECURSOR FOR CATALASE IN SUNFLOWER COTYLEDONS, Biochimica et biophysica acta. Molecular cell research, 1224(3), 1994, pp. 463-466
A cDNA from a sunflower (Helianthus annuus L.) library encoded a 56.8
kDa catalase peptide. N-terminal sequence comparisons to peroxisomal h
igher molecular weight precursors revealed conserved amino acid motifs
around the (putative) cleavage sites. These findings suggest that the
55 kDa catalase in sunflower cotyledons is synthesized at a higher mo
lecular weight.
