Identification of an intracellular β-glucosidase in Aspergillus niger with transglycosylation activity
Aspergillus niger is featured with its copious amount of extracellular β-glucosidase which is generally used to balance the cellulolytic enzyme cocktails for lignocellulose saccharification. However, whether or not A. niger produces any intracellular β-glucosidase remains obscure. In this study, we...

description | Aspergillus niger
is featured with its copious amount of extracellular β-glucosidase which is generally used to balance the cellulolytic enzyme cocktails for lignocellulose saccharification. However, whether or not
A. niger
produces any intracellular β-glucosidase remains obscure. In this study, we analyzed a total of fifteen putative β-glucosidase genes (
bgl
s) in
A. niger
CBS 513.88 genome and the five of them were predicted as intracellular
bgl
s due to the lack of signal peptide of extracellular proteins. After further characterization of these five genes through a
Saccharomyces cerevisiae
in vivo system, only An03g03740 (designated
bgl1B
) was confirmed to be a β-glucosidase gene. Western blot and mass spectrometry analysis confirmed BGL1B protein localization inside the cell. BGL1B exhibited the maximal activity at 40 °C and pH 5.6. The
K
m
for
p
-nitrophenyl-β-
d
-glucopyranoside and
K
i
for glucose were 0.233 ± 0.058 mM and 119.8 ± 4.35 mM, respectively. BGL1B showed a strong transglycosylation activity while hydrolyzing cellodextrins with sophorose, laminaribiose, and cellotriose formed from cellobiose, and sophorose and laminaribiose formed from cellotriose. The confirmation of the intracellular β-glucosidase BGL1B in
A. niger
further extends our understanding of how
A. niger
utilizes lignocellulose.
Key points
•
Identification of putative genes revealed a novel β-glucosidase in Aspergillus niger.
•
Newly identified β-glucosidase BGL1B was an intracellular enzyme of A. niger.
•
BGL1B exhibited a strong transglycosylation activity. |
