Description
Description
Attacins are small (~180-220aa), glycine-rich proteins with antimicrobial activity. Attacins are predicted to form a β-barrel structure. All, with the exception of AttD, are secreted. (Adapted from FBrf0241672 and FBrf0261536.)
Notes on Group

Unlike other Attacins that are immune-inducible, CG33493 is constitutively expressed.
