TABLE 3.

LCT CROP sequence identity and similarity

LCT % sequence identity (% similarity)a
TcdA TcdB TcsH TcsL
TcdB 37 (51)
TcsH 68 (77) 43 (57)
TcsL 36 (50) 75 (87) 43 (59)
TcnA 34 (45) 27 (40) 39 (57) 31 (48)

aSequence identity and similarity were calculated using Water (EMBOSS) local alignment. LCTs are from the following strains: C. difficile VPI 10463, P. sordellii VPI 9048, and C. novyi 19402. Under new subtyping analysis, TcdA and TcdB from C. difficile VPI 10463 are referred to as TcdA1 and TcdB1 (138).
