A non-substrate effector of p-hydroxybenzoate hydroxylase
(Elsevier, 1970-08-24)
A substrate analogue, 6-hydroxynicotinate (6-OHNA), facilitates reduction of the enzyme bound flavin by TPNH but is not hydroxylated in the reoxidation of the enzyme by oxygen. Binding of 6-OHNA to oxidized p-hydroxybenzoate ...
Variation in the primary structure of carbonic anhydrase B in man, great apes, and old world monkeys
(Elsevier, 1970-12-24)
The amino acid compositions and sequences of 15 homologous tryptic peptides of carbonic anhydrase B from man and 7 Old World primates were compared. Of the 133 residues examined, differences were noted at 8 presumably ...
Organization of the spermatozoon of Agriolimax reticulatus , the grey field slug (Pulmonata, Stylommatophora)
(Springer-Verlag, 1970-03)
Mature spermatozoa from the seminal vesicles of adult Agriolimax reticulatus have been studied by means of phase contrast and electron microscopy; sperm were either live, or sectioned or mounted whole and shadowed with ...
Thermoregulation and heterothermy in some of the smaller flying foxes (Megachiroptera) of New Guinea
(Springer-Verlag, 1970-06)
Body temperature, heterothermy, oxygen consumption, heart rate, and evaporative water loss were studied in four species of flying foxes (Megachiroptera), Dobsonia minor, Nyctimene major, Nyctimene albiventer , and Paranyctimene ...
An initial-value method for the solution of certain nonlinear diffusion equations in biology
(Elsevier, 1970)
The steady-state one-dimensional diffusion equation with a nonlinear source term is a class of differential equations governing the behavior of many biological systems. As with other types of nonlinear differential equations, ...
Two new ceruloplasmin variants in Negroes—Data on three populations
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-08)
Two new electrophoretic variants in human serum ceruloplasmin are described. The first, called Cp New Haven (CpNH), is determined by an allele at the same autosomal locus which controls the previously described CpA and CpB ...
Structure and function of mammalian ribosomes : I. Isolation and characterization of active liver ribosomal subunits
(Elsevier, 1970-10-14)
We have developed a method for preparation and purification of active ribosomal subunits from rat and mouse liver. Our technique involves incubating purified polysomes with all components for protein synthesis until all ...
