Expression of the structural mox genes in Paracoccus denitrificans follows wild-type regulation in mutants with a deletion in mxaY, the gene encoding the signal sensor
Article Abstract:
Analysis of the isolated characteristics of marked and unmarked mutations of mutated Paracoccus denitricans shows the MxaX response regulator is crucial to enable the mox genes to express themselves. The activation of MxaX requires more than one pathway. P. denitrificans oxidizes methanol, and forms formaldehyde when methanol substrates form. MxaX can be activated even in the absence of the signal sensor MxaY on a parallel signal transduction pathway.

Transcriptional co-regulation of five chitinase genes scattered on the streptomyces coelicolor A3(2) chromosome
Article Abstract:
Of the eight chitinase genes of Streptomyces coelicolor A3(2), five are induced by colloidal chitin and chitobiose with the latter inducing chitinase gene transcription sooner than the former. Data further suggest that glucose represses the expression of the five chitinase genes.

Family 19 chitinases of Streptomyces species: characterization and distribution
Article Abstract:
Results demonstrate that Streptomyces chitinase C resembles family 19 chitinases of plants and this property is also shared by the other family 18 bacterial chitinases. Amino acid sequence data indicate that chitinases of streptomyces species are family 19 class IV type.
