Methylmalonyl-CoA mutase (MCM) is an adenosylcobalamin-dependent enzyme that catalyses isomerization between methylmalonyl-CoA and succinyl-CoA (3-carboxypropionyl-CoA). Genetic deficiency of this enzyme in man causes an often fatal disorder of organic acid metabolism termed mut methylmalonicacidaemia. We report cloning of a mouse MCM cDNA and the characterization of its primary structure and b...

MCM-48 was surface modified via vapor-phase reactions with hexamethyldisilazane (CH(3)-MCM-48) and 3-aminopropyldimethylethoxysilane (NH(2)-MCM-48). (29)Si NMR confirmed that the resulting materials contained covalently attached trimethylsilane and 3-aminopropyldimethylsilane moieties, both important functionalities for bioseparation applications. The surface coverage was approximately 1.8 and ...

Many efficient algorithms and architectures have been introduced for the design of low complexity bitparallel Multiple Constant Multiplications (MCM) operation which dominates the complexity of many digital signal processing systems. On the other hand, little attention has been given to the digit-serial MCM design that offers alternative low complexity MCM operations. In this paper, we address ...

SUMMARY A new type of modulation called continuous-phase parallel-combinatory high-compaction multicarrier modulation (CPPC/ HC-MCM) is proposed. CPPC/HC-MCM employs the technique of continuous-phase modulation (CPM) and avoids the formation of amplitude gaps between two successive signals to enhance the spectral efficiency of conventional PC/HC-MCM. Results of simulations show that CPPC/ HC-MC...

The heterohexameric minichromosome maintenance protein complex (Mcm2-7) functions as the eukaryotic helicase during DNA replication. Mcm2-7 loads onto chromatin during early G1 phase but is not converted into an active helicase until much later during S phase. Hence, inactive Mcm complexes are presumed to remain stably bound from early G1 through the completion of S phase. Here, we investigated...

In 2001, IBM delivered to the marketplace a high-performance UNIX-class eServer based on a four-chip multichip module (MCM) code named Regatta. This MCM supports four POWER4 chips, each with 170 million transistors, which utilize the IBM advanced copper back-end interconnect technology. Each chip is attached to the MCM through 7018 flip-chip solder connections. The MCM, fabricated using the IBM...

Eukaryotes have six minichromosome maintenance (MCM) proteins that are essential for DNA replication. The contribution of ATPase activity of MCM complexes to their function in replication is poorly understood. We have established a cell-free system competent for replication in which all MCM proteins are supplied by purified recombinant Xenopus MCM complexes. Recombinant MCM2-7 complex was able ...
