Semen-derived enhancer of viral infection (SEVI) is the term given to the amyloid fibrils formed by a 39-amino acid fragment (PAP248-286) of prostatic acidic phosphatase (PAP) found in human semen. SEVI enhances human immunodeficiency virus (HIV) infectivity by four to five orders of magnitude (Münch et al., 2007). Here, we show by various biophysical techniques including Thioflavin T fluorescence, circular dichroism spectroscopy and transmission electron microscopy that fragments encompassing...[Show more]
