Amino-Acid Sequence of the Cytochrome c from the Yeast Hansenula anomala

Pyridine nucleotidenitrate reductase from Hansenula anomala a nitrate reducing yeast.

The recent elucidation of the enzyme systems involved in nitrate reduction in Neurospora crassa (Evans and Nason, 1952; Nason and Evans, 1953); Bacillus pumilis (Taniguchi et al., 1953); Escherichia coli (Taniguchi et al., 1956; Nicholas and Nason, 1955) and higher plants (Evans and Nason, 1953), has renewed interest in the general problem of nitrate reduction and nitrate assimilation in microo...

The amino acid sequence of wheat germ cytochrome c.

Determination of the complete amino acid sequence of wheat germ cytochrome c has shown that the molecule consists of a single polypeptide chain of 112 residues. On alignment with mammalian cytochromes, the peptide chain extends for 8 residues at the NH&erminal end. In contrast with other cytochromes that have a peptide chain longer than 104 residues, the NHt-terminal residue is Nacetylalanine. ...

The amino acid sequence of bovine heart cytochrome c.

Transport of malic acid and other dicarboxylic acids in the yeast Hansenula anomala.

DL-Malic acid-grown cells of the yeast Hansenula anomala formed a saturable transport system that mediated accumulative transport of L-malic acid with the following kinetic parameters at pH 5.0: Vmax, 0.20 nmol.s-1.mg (dry weight)-1; Km, 0.076 mM L-malate. Uptake of malic acid was accompanied by proton disappearance from the external medium with rates that followed Michaelis-Menten kinetics as ...

The Amino Acid Sequence of Cytochrome b,*

Calf liver microsomal apocytochrome bs was hydrolyzed with chymotrypsin and the resulting peptides were resolved on a Dowex 1 column. The isolation and partial amino acid sequences of the 10 chymotryptic peptides are described. The total amino acid composition of these peptides is equal to the sum of the residues present in the tryptic peptides. On the basis of the data obtained for the chymotr...
