Beta-defensin 1 is a protein that in humans is encoded by the DEFB1 gene. [5] [6]Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils.Members of the defensin family are highly similar in protein sequence.
Defensins are small cysteine-rich cationic proteins across cellular life, including vertebrate [1] and invertebrate [2] animals, plants, [3] [4] and fungi. [5] They are host defense peptides , with members displaying either direct antimicrobial activity , immune signaling activities, or both.
Beta defensins are a family of vertebrate defensins. The beta defensins are antimicrobial peptides implicated in the resistance of epithelial surfaces to microbial colonization. Defensins are 2 to 6 kDa, cationic, microbicidal peptides active against many Gram-negative and Gram-positive bacteria, fungi, and enveloped viruses, [ 1 ] containing ...
The cytoplasmic membrane is a frequent target, but peptides may also interfere with DNA and protein synthesis, protein folding, and cell wall synthesis. [10] The initial contact between the peptide and the target organism is electrostatic, as most bacterial surfaces are anionic, or hydrophobic, such as in the antimicrobial peptide Piscidin.
The protein encoded by this gene is secreted and is a member of the beta defensin protein family. Beta defensin genes are found in several clusters throughout the genome, with this gene mapping to a cluster at 20p13. The encoded protein is highly similar to an epididymal-specific secretory protein (ESP13.2) from cynomolgus monkey. [4]
Chickpeas contain about 15 grams of protein and 13 grams of fiber per 1-cup serving, plus 20% of the Daily Value for iron. The same serving of lentils provides about 18 grams of protein, 16 grams ...
