Starting Model(s)

Initial Refinement Model(s)
Type	Source	Accession Code	Details
experimental model	PDB	2SBL	FOR MOLECULAR REPLACEMENT: 1SBL FOR SOYBEAN LIPOXYGENASE-1. THE MODEL WAS TRUNCATED TO INCLUDE ONLY THE ATOMS (7854) COMMON WITH LIPOXYGENASE-3 SEQUENCE (ENTRY 1SBL WAS REPLACED LATER IN PDB BY 2SBL WITH BETTER REFINED MODEL).
