FIG. 2.

Cell wall proteome analysis of B. subtilis wild-type (wt), ΔyvrI, and ΔyvrL mutant strains in the presence (rows A to C, +phytate) and absence (rows D to E, −phytate) of 1% phytate. Each row shows proteins from cells harvested during early exponential-phase (OD₅₄₀, 2), mid-exponential-phase (OD₅₄₀, 3), late exponential-phase (OD₅₄₀, 5), and stationary-phase (OD₅₄₀, 8) growth (as monitored by OD₅₄₀ measurements). Positions of the OxdC and Hag (flagellin) protein are indicated. (A) Wild type; (B) yvrI deletion; (C) yvrL deletion with phytate; (D) wild type; (E) yvrL deletion without phytate.
