The Protein of an Aquatic Textile Fibre (Trichoptera: Stenopsychidae Marmorata)
Silks are insoluble protein polymers whose physical properties have enormous potential for biomaterials applications through genetic engineering.Caddis flies are considered underwater architects because most species use silt for building throughout their larval life.All larvae spin silk when they build their nets,retreats,cases,or cocoons.Just like the larvae of the midge,Chironomus tenruns,caddisfly spin underwater silk,Initially,silk proteins are part of the soluble intracellular protein pools of the peripheral secretory cells in which they are synthesized.Then subsequently secreted into the central lumen where they apparently assemble into soluble macromolecular complexes.Ultimately,silk protein complexes are aligned in parallel arrays and extruded.The silk filament of caddisflies,which is produced and persists in water,contained homologues of H-fibroin and L-fibroin chain of lepidoptera.The homologies of L-fibroin of Stenopsychidae marmorata and Hydropsychean gustipennis is 68％,Positives is 78％.It will be possible to use caddis-fly fibres for different technical purpose,especially for use in aquatic conditions,because natural caddis floss is made and used in water.
