... the geometry of the active site. The availability of crystal structures of TIMs from 21 sources and the large database of TIM sequences from various sources facilitate an analysis of mutational ... conse- quences of mutations. In the case of TIM, only nine of the 220–250 residues present in the sequences of the enzymes from diverse sources are indeed completely conserv...

... high degree of channeling of fructose 1,6-bisphosphate (Fru1,6P 2 )toCO 2 (99 ± 16% of the flux from Fru1,6P 2 channeled, P ¼ 0.005). This result requires that all of the downstream steps from Fru1,6P 2 to pyruvate ... rate of the evolution of 14 CO 2 from the earliest time point (see Results).

... problem of unscrambling English affixes. The role of affixes is crucial in the study of word-breaking practice. In the automatic determination of the parts of speech (a central feature of automatic ... essence of the problem of the definition of 'affix' lies here. It is not too hard to construct a sufficiently broad and inclusive definition; the construct...
