Abstract:

A repeating 11-mer amino acid sequence motif, first recognized in plant seed proteins, has been observed in such diverse organisms as the nematode Caenorhabditis elegans and the eubacteria Haemophilus influenzae and Dienococcus radiodurans. Amino acid preferences at each position in the motif are presented, as are dot matrix sequence comparisons between several of the proteins harboring the repeating motif. Although implicated in plant abiotic stress tolerance, no molecular function for the proteins carrying the motif has yet been uncovered.

More about this publication?

Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
