The title compound, C(16)H(20)N(2)O(2), was obtained by catalytic asymmetric cyclo-addition of trans-3-propyl-acrolein with 1-benzyl-idenepyrazolid-3-one betaine. There are two symmetry-independent mol-ecules in the asymmetric unit. In both mol-ecules, the two five-membered heterocyclic rings adopt envelope conformations.
Methyltransferases play crucial roles in many cellular processes, and various regulatory mechanisms have evolved to control their activities. For methyltransferases involved in biosynthetic pathways, regulation via feedback inhibition is a commonly employed strategy to prevent excessive accumulation of the pathways' end products. To date, no biosynthetic methyltransferases have been characteriz...
Breast cancer (BC) is one of the most common causes of death among women, and second in Iran. The objectives of this study were to determine the frequency of methyltetrahydrofolate-homocysteine methyltransferase (MTR) 2756 gene polymorphism in patients with breast cancer. For the first time, we evaluated these polymorphisms and effects on the breast cancer risk association in an Iranian sporadi...
The coding sequences of two S-adenosyl-L-homocysteine hydrolases (SAHases) were identified in yellow lupine by screenig of a cDNA library. One of them, corresponding to the complete protein, was sequenced and compared with 52 other SAHase sequences. Phylogenetic analysis of these proteins identified three groups of the enzymes. Group A comprises only bacterial sequences. Group B is subdivided i...
