Enantioselective biotransformation of sterically hindered amine substrates by the fungus Stemphylium lycopersici

Abstract: Here in, we contribute to the improvement of the biocatalytic toolbox for chiral amines synthesis. Interestingly, we have found that the crude enzymatic extract of the endophytic fungus S. lycopersici could accept bulky substrates with reasonable activity, compared to the wild-type transaminase already published over literature, and with high enantioselectivity.

“…The S. lycopersici endophytic fungus isolated from H. balsamifera leaves showed to be a promising species when cultured in media with high oil content (Figure 1), endorsing our previous report about its biotransformation potential. [15,16] The fungus extract showed significant lipolytic activity when assayed in the hydrolysis of olive oil by the titrimetric method, suggesting other enzymes in addition to aminotransferases previously found, in other conditions growth.…”

“…The procedures for obtaining the fungus S. lycopersici were previously described by our group. [15] The culture was stored at the Filamentous Fungi Culture Collection from Oswaldo Cruz Foundation (FIOCRUZ/CCFF) accredited by the Administrative Council of genetic patrimony under the number 010413/2012-0 (CGEN). The sequence obtained was deposited in the GenBank under the accession number KY198386.…”

“…La mayoría de las especies de Stemphylium son fitopatógenas de hábito necrótrofo y/o saprótrofo 31,57,76 . Sin embargo, también se han descripto especies de Stemphylium de hábitos endofíticos 60,[77][78][79][80] . Una especie de Stemphylium puede ser patógena necrótrofa en un hospedador, pero endófita en otro hospedador, además de saprótrofa en tejido vegetal muerto.…”

“…El tamaño esperado del genoma puede inferirse a partir de los datos del valor-C o, alternativamente, a partir de los enfoques basados en la frecuencia k-mer. Asimismo, la completitud de un genoma puede estimarse mediante herramientas bioinformáticas que inspeccionan en un ensamblaje genómico la presencia de colecciones de genes universales de copia única para el linaje taxonómico investigado162,175,184,185 .Se han realizado varios estudios centrados principalmente en la variación morfológica, fisiológica, patógena y genética en diferentes poblaciones de S. lycopersici, pero aún queda mucho por investigar sobre los mecanismos moleculares subyacentes a todos estos aspectos29,60,62,79 . En este sentido, el proyecto de secuenciación del genoma de S. lycopersici CIDEFI-216 podría arrojar luz sobre muchos de estos temas, como así también, podría contribuir a una mejor comprensión de la historia evolutiva de Stemphylium.…”
