... a given total flux is obviously equivalent to maintaining a given rate of biomass production at a minimum of the total flux. Insofar, the principle of maximal biomass production is a special case of ... the mathematical basis of the method. The second part presents two applications of the method to the metabolism of erythrocytes and of the microorganism, Metylobacterium ex...

... idea of the proof is to encode negation and the truth values of variables in features; to enforce clausal satisfication with a local autoseg- mental process, such as syllable structure; and to ... limits us to specifying a polynomial number of features and a polynomial number of rules. Since each feature corresponds to a tape square, ie., the ATM space resource,...

... localization of cystatin F, its restricted and readily regulated expres- sion [18], selective and not too potent inhibition of cathepsins are all in favor of the active role of cystatin F in processes of ... Higher dithiotreitol concentrations than previously reported [12] were needed to restore monomers and inhibi- tory activity under nondenaturing conditions. Loss of i...

... use of selective inhibitors as convenient tools to study the spe- cificity of the somatic form of ACE. Thus, with this approach, the catalytic property of each domain towards the hydrolysis of ... identification of a C-domain-specific inhibitor, RXPA380 [13], of human ACE may provide such an alternative strategy for studying inhibitor and substrate selectivity of any form of...

... range of structural diversity produced by a sequence of biosynthetic reactions. Cyclization of oxidosqualene is the ini- tial origin of structural diversity of skeletons in their biosynthesis, and ... modifi- cation of these carbon skeletons and transfer of the sugar moiety (Fig. 1). More than 80 different types of skeleton are generated at the cyclization step [7]. Success...
