The complex morphology of the nanopatterned siUca diatom cell walls has been found to be related to species-specific sets of polycationic peptides, so-called silaffins, which were isolated from diatom cell walls [82], The morphologies of precipitated sihca can be controlled by changing the chain lengths of the polyamines as well as by a synergistic action of long-chain polyamines and silaffins [83,84]. It has been proposed that the delicate pattern formation in diatom shells can be explained by phase separation of silica solutions in the presence of these polyamines [85]. Various linear synthetic analogs of the natural active polyamines in biosilica formation can accelerate the silicic acid condensation even more than the above mentioned... [Pg.85]

The Japanese species Penares cf. incrustans has also yielded penaramides, an inseparable mixture of long chain polyamines with two N-methylamide groups. These unique derivatives are potent inhibitors of the fixation of CD-conotoxin in N-type calcium channels (Ushio-Sata et al, 1996). Penaramides are the first non-peptide derivatives with this type of action. [Pg.699]

A series of sulfated long-chain polyamines (LCPAs) was isolated from the Japanese sponge Axinyssa aculeata collected ofFiriomote Island (Okinawa) and it was shown that these compounds are involved in silicon metabolism and the formation of sponge spicules (Matsxmaga et al, 2007). [Pg.982]
