M. Abebe et al., SIMULIDIN - A BLACK FLY (SIMULIUM-VITTATUM) SALIVARY-GLAND PROTEIN WITH ANTI-THROMBIN ACTIVITY, Journal of insect physiology, 41(11), 1995, pp. 1001-1006
A protein purified from the salivary gland lysate of female Simulium v
ittatum was found to inhibit bovine alpha-thrombin. This protein is st
able to heat, has a mass of 11,334 Da and is rich in threonine, Based
on N-terminal sequencing for the first 35 amino acids, no significant
sequence similarity with other proteins was detected, indicating that
this salivary component may be unique in structure, Because of its sou
rce and its anti-hemostatic properties, this protein has been named si
mulidin.
