Poulter, Charles Dale | Prenyltransferase. Kinetic studies of the 1'-4 coupling reaction with avian liver enzyme. | Prenyltransferase catalyzes the sequential, irreversible 1'-4 condensation of isopentenyl-PP with dimethylallyl-PP and geranyl-PP to yield farnesyl-PP. A kinetic study shows substrate inhibition by isopentenyl-PP at concentrations above 0.7 microM when the concentration of geranyl-PP is 1.0 microM o... | Birds; Kinetics; Structure-Activity Relationship; Substrate Specificity | 1979-10-10 |

Broughton, John | Size of the bursa of fabricius in relation to gonad size and age in laysan and black-footed albatrosses | Age determination can be difficult for birds that undergo little or no plumage change during life. This is the case for Laysan and Black-footed Albatrosses (Diomedea immutabilis and D. nigripes). The juvenile plumage for both these North Pacific albatrosses is completely grown by about five to six m... | Birds; Species; Development | 1994 |
