FIG. 3.

(A) SDS-PAGE of CWBP extracted from L16601 lyt⁺ (lane 1) and L16638 lytE (lane 2). Standard M_r proteins (Bio-Rad broad range) are also shown (lane 3). (B) Results of renaturation gel assay performed with CWBP extracted from L16601 (lane 1) and L16638 lytE (lane 2). Pictures of the gels were digitally recorded with a charge-coupled device camera (Vilbert Lourmat, Marme la Vallée, France) and processed by computer. Molecular weights of standard proteins are shown on the right (in thousands).
