Amorphous alumino phosphate (AP) and zirconium phosphate (ZP) materials possessing an ordered nanoporosity have been successfully synthesized by a hydrothermal method using a P123 block co-polymer as the structure directing agent. The materials exhibited excellent catalytic activity towards selective alkylation of phenol with cyclohexanol, where AP showed as high as 100% selectivity to produce ...

By incubating Ehrlich cells with isotopically labeled nitrogen mustards the relation between the extent of alkylation of cell constituents and the reduction of growth potential can be studied. Data obtained by such studies show that both CQM and HN2 react with a wide variety of cell constituents. Of the macromolecular constituents, the proteins undergo the greatest amount of alkylation, but the...

[reaction: see text]. The copper acetate mediated intramolecular O-arylation of phenols with phenylboronic acid pseudopeptides is the key step in the preparation of macrocyclic biphenyl ether hydroxamic acid inhibitors of collagenase 1 and gelatinases A and B. The intramolecular macrocyclization was found to be mild and tolerant of common chemical functionality. This methodology should provide ...

Pseudomonas aeruginosa KF702 (NBRC 110665) utilizes biphenyl as a sole source of carbon and degrades polychlorinated biphenyls (PCBs). Here, we report the 7,167,540-bp draft genome sequence of KF702, which contains 6,714 coding sequences and a 65.8 mol% G+C content. The strain possesses genes for biphenyl catabolism and other genes that mediate degradation of various aromatic compounds.

Pseudomonas putida KF715 (NBRC 110667) utilizes biphenyl as a sole source of carbon and degrades polychlorinated biphenyls (PCBs). Here, we report a complete genome sequence of the KF715 strain, which comprises a circular chromosome and four plasmids. Biphenyl catabolic genes were located on the largest plasmid, pKF715A.

Pseudomonas abietaniphila KF717 utilizes biphenyl as a sole source of carbon and energy and degrades polychlorinated biphenyls (PCBs). We report here the 6,930,016-bp genome sequence of this strain, which contains 6,323 predicted coding sequences (CDSs), including the biphenyl-utilizing bph gene cluster.

Alkylation-induced O(6)-methylguanine (O(6)MeG) DNA lesions can be mutagenic or cytotoxic if unrepaired by the O(6)MeG-DNA methyltransferase (Mgmt) protein. O(6)MeG pairs with T during DNA replication, and if the O(6)MeG:T mismatch persists, a G:C to A:T transition mutation is fixed at the next replication cycle. O(6)MeG:T mismatch detection by MutSalpha and MutLalpha leads to apoptotic cell de...

We report the draft genome sequence of Cupriavidus basilensis KF708 (NBRC 110671), which utilizes biphenyl as a sole carbon source and degrades polychlorinated biphenyls (PCBs). The KF708 strain possesses genes for biphenyl catabolism and other genes involved in various aromatic compounds.
