A lectin blot using Concanavalin A to stain mannose residues
was used to assess protein glycosylation of the mutant strains at
the restrictive temperature of 42 C. The blot revealed that the
mutant strains ASH84 (podB1) and R441 (swoP1) contain an altered
pattern of glycosylated proteins. The pattern observed in the
mutant strains when grown at 42 C differs from that of the comparable
wild type at the same temperature (Fig. 10). For example,
the protein bands present in the mutant strains between the 48
and 38 kDa markers and in the
