The screening method based on diameter of halos yielded only five strains with at least 20% more PG than wild t> e. Most attempts to enhance pectinase production have been made in filamentous fiingi, in which enzyme production is regulated by induction and catabolite repression mechanisms [8], By contrast, PG produced by marxianus is constitutive and not subject to catabolite repression [6], Failure to find greatly enhanced secretion levels is consistent with the idea of a constitutive gene that is capable of only modest further induction. PG was found in this study to be already the most prolific secreted protein of K. marxianus. 

Nucleotides These are polymers of the nucleic acids that constitute genes, and are used as therapeutics for their binding properties or genetic functions. They can be divided into two groups ... 

Constitutive genes are routinely transcribed, whereas inducible genes are transcribed only under appropriate circumstances. In prokaryotes, inducible genes and their regulatory sequences are grouped into operons. 

Brain constitutive gene e) >ression as revealed by itiRNA ontogeny data is potentially an irrportant mechanism for the turning on and turning off of itiRNAs in late gestation and the early neonatal period. Ihyroid hormone regulation must be si )eriirposed on this constitutive es ression. 

The statement that not the compound itself but its biosynthetic route has the taxonomical sig ni cance may be still valid. However, we know already that the biosynthetic route consists of complex metabolomic process including the genomic constitution, gene expression, transcriptional and translational regulation, enzyme activities at different biosynthetic levels, interactions with transporters, translocation, and spatial isolation (Dudareva et al., 2006 Dinesh and Nagegowda, 2010). The result of the enzymatic reaction is determined not only by the availability and constitution of the enzyme but also by the availability of precursors and different interactions therefore, the simple presence or absence of a certain enzyme in general cannot determine the nal product.
