STRUCTURE OF KRINGLE 4 AT 4C TEMPERATURE AND 1.67 ANGSTROMS RESOLUTION
Overview
Despite considerable effort to elucidate the functional role of the, kringle domains, relatively little is known about interactions with other, protein domains. Most of the crystal structures describe the interactions, at the kringle active site. This study suggests a novel way to interpret, structural results such as disorder located away from an active site. The, crystal structure of human plasminogen kringle 4 (PGK4) has been refined, against 10-1.68 A resolution X-ray data (R(merge) = 3.7%) to the standard, crystallographic R = 14.7% using the program X-PLOR. The crystals of PGK4, showed significant instability in cell dimensions (changes more than 1.5, A) even at 277 K. The refinement revealed structural details not observed, before [Mulichak, Tulinsky & Ravichandran (1991). ... [(full description)]
