X-ray coordinates defining the human papillomavirus E2 transactivation domain / inhibitor co-crystal and the inhibitor binding pocket

摘要

A crystallizable composition, comprising an PV E2 TAD-like polypeptide of SEQ ID NO.2 complexed with an inhibitor L. The invention also provides a method for producing the crystallized HPV E2 TAD-inhibitor complex (HPV E2 TAD-L) comprising: a) mixing purified HPV E2 TAD, contained in a purification buffer, with solublized inhibitor L to generate a complex solution containing the HPV E2 TAD-L complex; and b) crystallizing the complex from a) in a crystallization buffer. The invention also provides a method for producing crystallized apo HPV E2 TAD, comprising: a) mixing apo HPV E2 TAD, contained in a purification buffer, with a crystallization buffer. X-ray crystal structure coordinates the HPV E2 TAD-L complex, are also provided, which define an inhibitor binding pocket. The inhibitor binding pocket is useful for screening potential small molecule inhibitors that bind to the pocket.
