Expression at 279 K, purification, crystallization and preliminary X-ray crystallographic analysis of a novel cold-active β-1,4-d-mannanase from the Antarctic springtail Cryptopygus antarcticus

A cold-active β-1,4-d-mannanase from the Antarctic springtail C. antarcticus (CaMan) has been expressed, purified and crystallized. The CaMan crystal belonged to space group P212121, with unit-cell parameters a = 73.40, b = 83.81, c = 163.55 Å, and diffracted to 2.35 Å resolution. A 2.40 Å resolutio...

Description
Summary:A cold-active β-1,4-d-mannanase from the Antarctic springtail C. antarcticus (CaMan) has been expressed, purified and crystallized. The CaMan crystal belonged to space group P212121, with unit-cell parameters a = 73.40, b = 83.81, c = 163.55 Å, and diffracted to 2.35 Å resolution. A 2.40 Å resolution data set was also collected from a CaMan–mannopentaose complex crystal.
