Abstract

Pantothenate kinase is an essential enzyme in the bacterial life cycle. It catalyzes the phosphorylation of pantothenate (vitamin B5) to 4'-phosphopantothenate, the first step in the coenzyme A biosynthetic pathway. The enzyme from Mycobacterium tuberculosis, MW 35.7 kDa, has been cloned, expressed, purified and crystallized in two different trigonal crystal forms, both belonging to space group $P3_{1}21$. Two complete data sets of resolution 2.5 Å (form I) and 2.9 Å (form II) from crystals with unit-cell parameters a = b = 78.3, c = 115.45 Å and a = b = 107.63, c = 89.85 Å, respectively, were collected at room temperature on a home X-ray source. Structures of both crystal forms were solved for one subunit in the asymmetric unit by molecular replacement.
