일반 설명
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research.
애플리케이션
Petctinase from Aspergillus niger has been used:
- for protoplasts liberation
- in the protoplast enzyme mixture for enzyme digestion
- to conduct partial saccharification of sugars
- to study their role in the invasion of plant tissues by phytopathogens, the spoilage of produce and various food processing and plant biotechnology applications
Used in plant protoplast preparation to digest cell wall prior to organelle isolation.
생화학적/생리학적 작용
Pectolytic enzyme preparation produced from a selected strain of Aspergillus niger: contains mainly pectintranseliminase, polygalacturonase, and pectinesterase and small amounts of hemicellulases and cellulases. Pectinases hydrolyses pectin, which is a component of the cell wall. They may attack methyl-esterified pectin or de-esterified pectin. It is a source of pectinase activity, also containing cellulase and hemicellulase activities.Pectinase catalyzes the random hydrolysis of a-(1-4)-Dgalactosiduronic linkages in pectin and other galacturonans.
단위 정의
One unit will liberate 1.0 μmole of galacturonic acid from polygalacturonic acid per min at pH 4.0 at 25 °C.
물리적 형태
Solution in 40% glycerol

If two related plant species hybridize, their genomes may be combined and duplicated within a single nucleus, thereby forming an allotetraploid. How the emerging plant balances two co-evolved genomes is still a matter of ongoing research. Here, we focus on

Good preparations are essential for informative analysis of both somatic and meiotic chromosomes, cytogenetics, and cell divisions. Fluorescent chromosome staining allows even small chromosomes to be visualized and counted, showing their morphology. Aneuploidies and polyploidies can be established for species

Structural chromosome rearrangements involving translocations, fusions and fissions lead to evolutionary variation between species and potentially reproductive isolation and variation in gene expression. While the wheats (Triticeae, Poaceae) and oats (Aveneae) all maintain a basic chromosome number of x=7, genomes
