Incorporation of β-selenolo[3,2-b]pyrrolyl-alanine into proteins for phase determination in protein X-ray crystallography

, 2001
β-Selenolo[3,2-b]pyrrolyl-l-alanine that mimics tryptophan with the benzene ring of the indole moiety replaced by selenophene, was incorporated into human annexin V and barstar.

Overcoming non-isomorphism by phase permutation and likelihood scoring: solution of the TrpRS crystal structure.

Acta Crystallographica Section A Foundations of Crystallography, 1994
Entropy maximization to maximum likelihood, constrained jointly by the best available experimental phases and by a sufficiently good envelope, can bring about substantial model-independent map improvement, even at medium (3.1 A) resolution [Xiang, Carter,

Isomorphism of lattices of subgroups of the layer and rod groups with sublattices of subgroups of the space groups.

Acta Crystallographica Section A Foundations of Crystallography, 2011
Following a brief overview of current knowledge on lattices of subgroups of the space groups, it is shown that in the case of reducible space groups those lattices contain sublattices which are lattice isomorphic to the lattices of subgroups of layer and
