Laccases are blue multicopper enzymes, capable of oxidizing diverse aromatic and non-aromatic compounds of industrial interest, concomitantly with reduction of molecular oxygen to water. Tolerance to extreme conditions, such as high temperature, salinity or extreme pH, is required for practical industrial applications. Here we focus on bacterial laccases from the phylum Actinobacteria, notably the order Actinomycetales. Currently, less than 10 enzymes have been properly characterized, all belonging to genus Streptomyces, but it is noteworthy that all of them have exhibited industrially important properties. Furthermore, studies with enzymes from this phylum revealed a novel molecular structure of laccases, providing the basis for a distinct family, the two-domain laccases. The relevant traits of actinomycetes laccases emphasize the need for more studies involving the isolation of this bacterial group from lignin-rich environmental samples, detection of their laccase activity and thereafter, characterization of the proteins and related genes. The nonhomogeneous responses of actinomycetes laccases to traditional inhibitors, substrates or metal ions have challenged the currently accepted “laccase concept”. Finally, considering that distinguishing laccase activity in vitro from other ligninolytic enzymes becomes a difficult task due to overlaps in catalytical properties of the enzymes, we proposed a simple flow chart to help experimental assays.

Members of the ERF Family of Transcription Factors play an important role in plant development and gene expression that regulates responses to biotic and abiotic *** work identified 36 ERF family genes in Coffea arabica within the AP2/ERF full domain,using the EST-based genomic resource of the Brazilian Coffee Genome *** ERF family genes were classified into nine of the ten existing groups through phylogenetic analysis of the deduced amino acid sequences and comparison with the sequences of the ERF family genes in *** addition to the AP2 domain,other conserved domains were identified,typical of members of each *** in silico analysis and expression profiling showed high levels of expression for libraries derived from tissues of fruits,leaves and flowers as well as for libraries subjected to water *** results suggest the participation of the ERF family genes of *** in distinct biological functions,such as control of development,maturation,and responses to water *** results of this work imply in the selection of promising genes for further functional characterizations that will provide a better understanding of the complex regulatory networks related to plant development and responses to stress,opening up opportunities for coffee breeding programs.
