Three-Dimensional Structure of Adenosylcobinamide Kinase
... the enzyme is a trimer where the subunits are arranged as a pinwheel with a prominent cleft that might serve as the binding site for adenosylcobinamide (9). Each subunit consists of six parallel β-strands and a C-terminal antiparallel β-strand flanked by several R-helices. The fold is similar to sev ...
