Functional Characterization of Two M42 Aminopeptidases Erroneously Annotated as Cellulases
Several aminopeptidases of the M42 family have been described as tetrahedral-shaped dodecameric (TET) aminopeptidases. A current hypothesis suggests that these enzymes are involved, along with the tricorn peptidase, in degrading peptides produced by the proteasome. Yet the M42 family remains ill defined, as some members have been annotated as cellulases because of their homology with CelM, form...
متن کاملArginine regulation in Thermotoga neapolitana and Thermotoga maritima.
Experimental data and in silico analyses of sequenced bacterial genomes indicate that arginine repressor (ArgR) proteins and their respective target sites are surprisingly well conserved in very diverse bacteria. Arginine regulation therefore constitutes an interesting model system from the study of evolutionary aspects of bacterial regulation. Moreover, arginine repressor molecules are multifu...
متن کاملPyruvate decarboxylase activity of the acetohydroxyacid synthase of Thermotoga maritima
Acetohydroxyacid synthase (AHAS) catalyzes the production of acetolactate from pyruvate. The enzyme from the hyperthermophilic bacterium Thermotoga maritima has been purified and characterized (kcat ~100 s-1). It was found that the same enzyme also had the ability to catalyze the production of acetaldehyde and CO2 from pyruvate, an activity of pyruvate decarboxylase (PDC) at a rate approximatel...
متن کاملThe Temperature Dependent Proteomic Analysis of Thermotoga maritima
Thermotoga maritima (T. maritima) is a typical thermophile, and its proteome response to environmental temperature changes has yet to be explored. This study aims to uncover the temperature-dependent proteins of T. maritima using comparative proteomic approach. T. maritima was cultured under four temperatures, 60°C, 70°C, 80°C and 90°C, and the bacterial proteins were extracted and electrophore...
متن کاملThe Genome Organization of Thermotoga maritima Reflects Its Lifestyle
The generation of genome-scale data is becoming more routine, yet the subsequent analysis of omics data remains a significant challenge. Here, an approach that integrates multiple omics datasets with bioinformatics tools was developed that produces a detailed annotation of several microbial genomic features. This methodology was used to characterize the genome of Thermotoga maritima--a phylogen...
