FIG. 1. — Purification of GroEL from a gyrB mutant of B. burgdorferi. (A) The 68-kDa protein (identified as GroEL) was purified by column chromatography. Lane 1, cell lysate; lane 2, flowthrough from a heparin column; lane 3, pooled fractions after elution from a phenyl Superose column; lane 4, pooled fractions after elution from a Mono-Q column. Molecular masses are in kilodaltons. (B) N-terminal sequence of the 68-kDa protein and alignment with GroEL (BB0649; GenBank accession no. AE001166) (6).
