| Abstract |
Six-stranded beta barrels with a pseudo-twofold axis are found in several proteins. One group comprises a Greek-key structure with all strands antiparallel; an example is the N-terminal domain of ferredoxin reductase. Others involve parallel strands forming two psi structures (the double-psi beta barrel). A recently discovered example of the latter class is aspartate-alpha-decarboxylase (ADC) from Escherichia coli, a pyruvoyl-dependent tetrameric enzyme involved in the synthesis of pantothenate. |
