Polymer substrate

Polyethyleneimine (PEI) is a novel polymer that contains multiple amine groups that are suitable for chelation with many heavy metal ions (HMI). Anchoring PEI onto the surface of a solid substrate has been widely adopted to develop adsorbent materials with the hope of combining the HMI chelating ability of PEI with the heterogeneity of the substrate.

The research using some advanced, environmentally friendly materials such as water-absorbing polymers and soil-binding polymers in potting medium is also a new direction to improve water retention. The study of manufacturing polybags with different degradation time combined with the use of SAP and PAM in substrates of pots to improve some features of the current nursery.

In this review, we summarize recent progress in studying three main classes of prenyltransferases: (a) isoprenyl pyrophosphate synthases (IPPSs), which catalyze chain elongation of allylic pyrophosphate substrates via consecutive condensation reactions with isopentenyl pyrophosphate (IPP) to generate linear polymers with defined chain lengths; (b) protein prenyltransferases, which catalyze the transfer of an isoprenyl pyrophosphate (e.g. farnesyl pyrophosphate) to a protein or a peptide; (c) prenyltransferases, which catalyze the cyclization of isoprenyl pyrophosphates.

Dispersin B (DspB), a family 20b-hexosaminidase from the oral pathogen Aggregatibacter actinomycetemcomitans, cleaves b(1,6)-linked N-acetylglu-cosamine polymer. In order to understand the substrate specificity of DspB, we have undertaken to characterize several conserved and noncon-served residues in the vicinity of the active site.

Cationic cell wall-bound peroxidase (CWPO-C) has the capability to oxi-dize sinapyl alcohol, ferrocytochromec, and synthetic lignin polymers, unlike most peroxidases that have been characterized in flowering plants, such as horseradish peroxidase and Arabidopsis thalianaperoxidase A2.
