Trichomonas vaginalis Cysteine Proteinases: Iron Response in Gene Expression and Proteolytic Activity

Figure 3

Classification of ~440 peptidase coding genes found in the T. vaginalis genome sequence database (http://www.trichdb.org/) as serine, threonine, aspartic, metallo-, or cysteine proteinase. The number of members per type of proteinases is shown in parenthesis: cysteine , metallo- , serine , threonine , and aspartic [25].
