SKAP2 and infection: Compared to the other Mucor species, 1,354 open reading frames were unique to M. velutinosus B5328, including 66 putative genes predicted to encode secreted proteins, several of which are secreted aspartyl proteinases (SAPs), which are implicated in numerous functions during the infection process of fungi, such as Candida albicans (Table 2) [40, 41].
