In this study, we detail the specificity of an aspartic peptidase from Rhizomucor miehei and evaluate the effects of this peptidase on clotting milk using the peptide sequence of k-casein (Abz-LSFMAIQ-EDDnp) and milk powder. Molecular mass of the peptidase was estimated at 37 kDa, and optimum activity was achieved at pH 5.5 and 55 °C. The peptidase was(More)
The entomopathogenic fungus Metarhizium anisopliae is used to control insect pests. This species is specialized for the secretion of an enzymatic complex consisting of proteases, lipases, and chitinases related to pathogenicity and virulence. In this context, the secretomes of strains IBCB 167 and IBCB 384 of M. anisopliae var. anisopliae, grown under(More)
Nucleoside diphosphate kinases play a crucial role in the purine-salvage pathway of trypanosomatid protozoa and have been found in the secretome of Leishmania sp., suggesting a function related to host-cell integrity for the benefit of the parasite. Due to their importance for housekeeping functions in the parasite and by prolonging the life of host cells(More)
This paper describes the concept of a modular test code developed to reside in Microcontroller Units (MCUs) with Read-Only Memory (ROM) to make easier the test bench evaluation of integrated circuit (IC) prototypes designed at Brazil Semiconductor Technology Center (BSTC). MCU standard input/output ports are used to select independent operating modes and to(More)
Target prediction is generally the first step toward recognition of bona fide microRNA (miRNA)-target interactions in living cells. Several target prediction tools are now available, which use distinct criteria and stringency to provide the best set of candidate targets for a single miRNA or a subset of miRNAs. However, there are many false-negative(More)
