Abstract

A genomic clone encoding a new member of attacin, an insect antibacterial protein, was isolated from a genomic library of the silkworm, Bombyx mori, and the nucleotide sequence of the 5'-upstream region was determined. The region contained Bm 1, a highly repetitive element of B. mori and a lipopolysaccharide (LPS) response element (RE)(NF-kappaB binding site), CAAT box and TATA box. Northern blot analysis showed that the attacin gene expression was rapidly induced by bacterial cell wall components such as LPS from Escherichia coli and peptidoglycan (PG) from Micrococcus luteus, suggesting that attacin plays an important role in an early phase of the self-defense system upon bacterial infection.

Bacterial Cell Wall Structure (ASM)

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
