Crystallization and preliminary X-ray analysis of the human respiratory syncytial virus nucleocapsid protein.

ABSTRACT: Human respiratory syncytial virus (HRSV) has a nonsegmented negative-stranded RNA genome which is encapsidated by the HRSV nucleocapsid protein (HRSVN) that is essential for viral replication. HRSV is a common cause of respiratory infection in infants, yet no effective antiviral drugs to combat it are available. Recent data from an experimental anti-HRSV compound, RSV-604, indicate that HRSVN could be the target site for drug action. Here, the expression, purification and preliminary data collection of decameric HRSVN as well as monomeric N-terminally truncated HRSVN mutants are reported. Two different crystal forms of full-length selenomethionine-labelled HRSVN were obtained that diffracted to 3.6 and approximately 5 A resolution and belonged to space group P2(1)2(1)2(1), with unit-cell p
