Insights on Structure and Function of a Late Embryogenesis Abundant Protein from Amaranthus cruentus: An Intrinsically Disordered Protein Involved in Protection against Desiccation, Oxidant Conditions, and Osmotic Stress

Front Plant Sci
PMCID: 5384071
PMID: 28439280
DOI: 10.3389/fpls.2017.00497

[…] ences, a search was performed using protein BLAST algorithm and multiple alignment was carried out with the sequences of the highest similarity matches (Figure ). A search of related sequences in the LEAPdb database () confirmed that all these sequences are grouped in the LEA_4 Pfam (PF02987). According to the classification proposed by , in this family are included LEA proteins from Group 3, such […]


Comparison of Amino Acids Physico Chemical Properties and Usage of Late Embryogenesis Abundant Proteins, Hydrophilins and WHy Domain

PLoS One
PMCID: 4190154
PMID: 25296175
DOI: 10.1371/journal.pone.0109570

[…] Data about LEAPs contained in LEAPdb were used. LEAPs have been rigorously classified into 12 non-overlapping classes. Each class contains various number of sequences characterized by: (i) a unique amino acid motif; (ii) a homoge […]


Computational and Statistical Analyses of Amino Acid Usage and Physico Chemical Properties of the Twelve Late Embryogenesis Abundant Protein Classes

PLoS One
PMCID: 3353982
PMID: 22615859
DOI: 10.1371/journal.pone.0036968

[…] structured proteins (FS - 158 sequences). The size of these datasets is comparable to that of the 12 LEAP classes, and they allow a more comprehensive comparison of LEAP classes structural properties.LEAPdb provides a large number of physico-chemical properties: number of amino acids (length), molecular weight, isoelectric point, FoldIndex , mean (reduced) net charge at pH 7, mean hydrophilicity , […]
