Dendroid

The product crystals were agglomerates of needles or dendrites. Loose floes of dendroid strontium carbonate are compacted by agitation, which is an important factor in controlling the habit of product particles. Semi-batch operation produces larger particles compared to batch or continuous operation.

Scheme 3 Synthesis of 3-D-GalpNAcA-(l -> 4)-d-G1c/>NAc by coupled use of galactose oxidase from Dactylium dendroides and P-W-acetylhexosaminidase from Talaromyces flavus, followed by in situ chemical oxidation.76...

In early 1990 it became apparent that the structure of galactose oxidase from Dactylium dendroides was about to emerge. A 2.5 A multiple isomor-phous replacement (MIR) map based on area detector data from a native and three derivative crystals yielded a polypeptide chain tracing. The refined structure at 1.9 A (R = 0.179) (Ito et al., 1991) shows that galactose oxidase consists of three domains, each of which is predominandy jS...

The cyclic hexapeptide, waiakeamide (447) was isolated from an Indonesian collection of Ircinia dendroides [373]. Haliclona nigra from Papua New Guinea contained two cyclic hexapeptides, haligramides A (448) and B (449). They showed an unusual activity pattern in the National Cancer Institute (NCI) 60 cell-line panel [374],... 

An increased SOD capacity after copper supply was also found in other organisms (Shatzman and Kosman, 1978, in the fungus Dactylium dendroides Naiki, 1980, Sac-charomyces Ljutakova et al., 1984, rat liver Lee and Hassan, 1985, Saccharomyces). The increased biosynthesis of SOD in copper-treated yeast was suggested to be the result of an enhanced intracellular 02 flux (Lee and Hassan, 1985). 

The cold-hardy beetle Dendroides canadensis. A very different scenario from those presented above can be sketched for a freeze-avoiding insect from the temperate zone, where the threat of freezing, while only seasonal, is much more severe than that faced by fishes from high latitudes. One of the best-studied freeze-avoiding insects is the beetle Dendroides canadensis (Duman, 2001 Duman et al., 1993). Compared to freeze-avoiding fishes, D. canadensis mounts a much more extensive freeze-avoidance response and...

GOase from D. dendroides has been crystallised from acetate buffer at pH 4.5 using ammonium sulphate as precipitant. The structure has been solved by the multiple isomorphous replacement method using three heavy atom derivatives and the model refined to 1.7 resolution to allow detailed structural analysis (Ito et al., 1991 Ito et ah, 1994).

Crook and Johnston and Martin and Adams were unable to find uronic acids in the cell walls of fungi. However, 2 % of a glucuronic acid was detected in the dry cells of Dactylium dendroides, and lesser proportions in Aspergillus niger (0.1 %), Penicillium album (0.2%), a Fusarium sp. (0.5%), and an Alternaria sp. (0.7%). Glucuronic acid residues are apparently present in the cell walls of Neurospora crassa. ...
