It is thought that<unk>  evolved from a zoophilic ancestor, establishing itself ultimately as an exclusive agent of dermatophytosis on human hosts. Genetic analyses of T.<unk>  have revealed the presence of heat shock proteins, transporters, metabolic enzymes and a system of up-regulation of key enzymes in the glyoxylate cycle. The species secretes more than 20 different proteases, including exopeptidases and endopeptidases. These proteases allow T.<unk>  to digest human keratin, collagen and elastin; they have an optimum pH of 8 and are calcium dependent. Although T.<unk>  shares phylogenetic affiliations with other dermatophytes, it has a distinctive protein regulation system.
