Ome (Fig 1C). Within the predicted secretomes, 478 (in a. alternata) to 535 (in P. sporulosum) proteins were classified inside CAZy and MEROPS functional groups.Secretome diversity across broad functional groupsCategorizing the proteins in each experimental secretome based on broad functional groups in accordance with the CAZy and MEROPS databases reveals a striking similarity in secretome functional diversity among the 4 organisms (Fig 1A). The total proportion of CAZymes identified within the secretomes ranged from 22 in P. sporulosum to 28 within a. alternata and consisted predominantly of glycoside hydrolases (GHs; 12?5 ) and redox-active auxiliary activities (AAs; 5? ) in all 4 fungi. Peptidases comprised 12?3 of identified proteins in every with the fungal secretomes, although lipases comprised only 1 . Identified proteins which can be not viewed as by the CAZy or MERPOS databases had been categorized as “other” and constituted a large portion on the secretome for each fungus, ranging from 47 in a. alternata to 53 in Stagonospora sp. Around one-third of “other” identified proteins have been redox-active and includedPLOS One particular | DOI:ten.1371/journal.pone.0157844 July 19,7 /Secretome Profiles of Mn(II)-Oxidizing FungiPLOS One particular | DOI:10.1371/journal.pone.0157844 July 19,eight /Secretome Profiles of Mn(II)-Oxidizing FungiFig 1.

Non-redox active “other” proteins varied broadly in predicted function and incorporated lots of proteins most likely of intracellular origin. Hypothetical proteins, for which no function might be predicted determined by genome annotations in addition to a BLAST evaluation against sequenced fungal genomes in NCBI and UniProt, comprised 12?four of the fungal secretomes. When only contemplating experimentally identified proteins that are predicted to become secreted, the proportion of “other” proteins decreased substantially and represented only 22?four on the secretomes, down from an typical of 50 when all experimentally identified proteins had been regarded as (Fig 1B). Within the complete predicted secretomes, the proportion of hypothetical proteins enhanced virtually 3-fold, from 12?4 inside the experimental secretomes as much as 32?six within the predicted secretomes (Fig 1C). Also, the ratio of peptidases to GHs progressively decreased from an average of 0.9 in the experimental secretomes across the 4 fungi (e.g., 13 /14 in Pyrenochaeta sp.), to 0.7 inside the portion of experimental secretomes predicted to be secreted, and ultimately to 0.four within the complete predicted secretomes (Fig 1). All of those observations had been constant across all 4 organisms.
