| control of enzyme activity in growing bacterial cells by concerted feedback inhibition. | amino acids of the aspartic acid family are synthesized in bacteria through a multistep branched pathway. in the photosynthetic bacterium rhodopseudomonas capsulatus, the enzyme that catalyzes the first step is specifically inhibited by a combination of two end-product amino acids. evidence is presented for operation of this kind of "concerted" feedback control as a regulatory device in growing cells. | 1965 | 14281723 |

| effect of lipids and organic solvents on the enzymic formation of zinc protoporphyrin and haem. | 1. differences observed in earlier work between the enzymic chelation with protoporphyrin of zn(2+) and fe(2+) ions respectively have now been explained as being caused by the presence of peroxides in the ether used in the enzyme assay. the inhibitory effect of peroxides is established by the reducing agent, which is present in the assay for chelation of iron but not in that for zinc. there are now no reasons for the belief that two different enzymes catalyse formation of complexes with zinc and ... | 1966 | 5938631 |
| electrophoretic and other studies on haem pigments from rhodopseudomonas palustris: cytochrome 552 and cytochromoid c. | 1. cytochrome 552 and cytochromoid c were extracted from rhodopseudomonas palustris cells, purified and obtained in crystalline form. 2. extinction ratios and amino acid compositions of the two pigments are reported. 3. when subjected to starch-gel electrophoresis in borate buffer, ph8.8, each pigment migrated towards the cathode; oxidized cytochromoid c migrated more rapidly than its reduced form. 4. by a determination of electrophoretic mobilities in buffers of i0.1 by using the moving-boundar ... | 1966 | 5941351 |
