Large (L) granules(1) The L-granules consist of approximately 20 proteins with molecular weights ranging from 8 to 123 kDa [19].
(2) After isolating the L-granules, the extract showed that it caused the LPS to gel [29].
Small (S) granules(1) The S-granules include at least six proteins with molecular weights less than 30 kDa, as well as the antimicrobial peptide tachyplesin and its derivatives. Recent studies on S-granules have revealed that they also accumulate tachycitin, tachystatins, and large defensin in addition to tachyplesins (all of which are also found in L-granules), all of which have antibacterial properties against Gram-positive and Gram-negative bacteria as well as fungus [3033].
