Function

[C16MO_PSEPU] Involved in the degradation of (-)-camphor. Catalyzes the lactonization of the 3,6-diketocamphane via the Baeyer-Villiger oxidation to produce the unstable lactone (-)-5-oxo-1,2-campholide that presumably undergoes spontaneous hydrolysis to form 2-oxo-delta(3)-4,5,5-trimethylcyclopentenylacetic acid. It acts only on bicyclic ketones.[1] [2]

Publication Abstract from PubMed

The efficiency of the cross-rotation function step of molecular replacement (MR) is intrinsically limited as it uses only a fraction of the Patterson vectors. Along with general techniques extending the boundaries of the method, there are approaches that utilize specific features of a given structure. In special cases, where the directions of noncrystallographic symmetry axes can be unambiguously derived from the self-rotation function and the structure of the homologue protein is available in a related oligomeric state, the cross-rotation function step of MR can be omitted. In such cases, a small number of yet unknown parameters defining the orientation of the oligomer and/or its internal organization can be optimized using an exhaustive search. Three difficult MR cases are reported in which these parameters were determined and the oligomer was positioned according to the maximal value of the correlation coefficient in a series of translation searches.
