          Abstract

          We introduce a new approach to investigate the dual nucleotides compositions of 11 Gram-positive and 12 Gram-negative eubacteria recently studied by Sorimachi and Okayasu. The approach firstly obtains a 16-dimension vector set of dual nucleotides by PN-curve from the complete genome of organism. Each vector of the set corresponds to a single gene of genome. Then we reduce the 16-dimension vector set to 2-dimension by principal components analysis (PCA). The reduction avoids possible loss of information averaging all 16-dimension vectors. Then we suggest a 2D graphical representation based on the 2-dimension vector to investigate the classification patters among different organisms.

            An extension of Chou's graphic rules for deriving enzyme kinetic equations to systems involving parallel reaction pathways.

            H Deng, G. H. Zhou (1984)
            An extension has been made to the Chou's graphic rules in order to cover those enzyme-catalysed reaction systems in which there are two or more parallel reaction routes between any two enzyme species.

              Graphical rules for enzyme-catalysed rate laws.

              S Forsén, K R Chou (1980)
              Two graphical rules for calculating the reaction rates of steady-state enzyme-catalysed systems are presented. According to Rule 1, the number of non-zero terms can be easily calculated, which is useful to check the results and avoid mistakes. Rule 2 provides a new graphical method, which will be much more effective than the existing methods in dealing with complicated problems. In addition, during the process of deriving Rule 1, the mathematical principles of the Wong-Hanes structural rule have been naturally obtained too.
