“…Isoprenoids are an extensive group of natural products with diverse structures consisting of various numbers of fivecarbon isopentenyl pyrophosphate (IPP) units [1,2]. The more than 23 000 isoprenoid compounds identified thus far serve a variety of essential biological functions in Eukarya, Bacteria and Archaea.…”

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. The prenyltransferase products are widely distributed in nature and serve a variety of important biological functions. The catalytic mechanism deduced from the 3D structure and other biochemical studies of these prenyltransferases as well as how the protein functions are related to their reaction mechanism and structure are discussed. In the IPPS reaction, we focus on the mechanism that controls product chain length and the reaction kinetics of IPP condensation in the cis-type and trans-type enzymes. For protein prenyltransferases, the structures of Ras farnesyltransferase and Rab geranylgeranyltransferase are used to elucidate the reaction mechanism of this group of enzymes. For the enzymes involved in cyclic terpene biosynthesis, the structures and mechanisms of squalene cyclase, 5-epi-aristolochene synthase, pentalenene synthase, and trichodiene synthase are summarized.

“…A collaboration with Prof. Rene Rodriguez, Idaho State University, was initiated in order to develop a PECVD metal-Ge 2 Se 3 film deposition process [46][47][48][49][50][51]. After investigating blanket films for stoichiometries, an optimum set of film deposition conditions was determined and the film was deposited on wafers fabricated at Boise State that were processed to the bottom electrode via opening level.…”

“…To understand why this is the case it is necessary to present some background material on the nature of bridewealth in Lesotho. Bridewealth in Lesotho has been described at length elsewhere (Murray 1977(Murray , 1981Ashton 1967;Ferguson 1985Ferguson , 1990Poulter 1976;cf. also, for Botswana, Comaroff 1980).…”

The Cultural Topography of Wealth: Commodity Paths and the Structure of Property in Rural Lesotho

Discussions of poverty and wealth often assume that wealth is a measurable substance, the possession of which can be indexed on a linear scale, from high to low. This article contests this implicit assumption, arguing that wealth‐holding is always complicated by the fact that exchange is culturally regulated, and guided along approved paths. An analysis of domains of wealth in a rural Lesotho village illustrates the point. Wealth‐holding here is clearly unequal, but cultural, legal, and moral paths governing economic exchanges between different categories of property mean that the holdings of different households are in important ways incomparable, and that their wealth is different in kind, and not only in amount. The attempt to locate households economically in such a setting thus requires mapping a politicocultural “topography” of channels facilitating the flow of commodity exchange, dams obstructing, slowing, or filtering it, and furrows temporarily diverting the flow from one channel or dam into another. A meaningful ranking of wealth‐holding must include a cultural analysis of commodity paths and the structure of property.
