Carotenoids in the peripheral light-harvesting complexes (LH2) of the green mutant (GM309) of Rhodobacter sphaeroides were identified as containing neurosporenes, which lack the polar CH(3)O group, compared to spheroidenes in native-LH2 of R. sphaeroides 601. After LH2 complexes were treated

dUTP nucleotidohydrolase (dUTPase, EC 3.6.1.23) from E. coli contains a total of six tyrosine residues per trimer. About half of them were found to be susceptible to acetylation with N-acetylimidazole or to nitration with tetranitromethane with concomitant loss of activity.

Reaction of ovine prolactin (oPRL) with a 150-fold molar excess of N-acetylimidazole over protein content resulted in the modification of 2.5 tyrosine residues and 1.2 lysine residues. Acetylation greatly decreased the in vitro binding capacity to lactogenic sites. This binding
To study its contribution to the assembly of the green plant manganese stabilizing protein (MSP) into photosystem II (PSII), tyrosine residues were specifically acetylated using N-acetylimidazole (NAI). In soluble MSP, three groups of Tyr residues could be differentiated by NAI

Aspartokinase III (AK III) has been purified from a plasmid-containing strain of Escherichia coli. The enzyme shows broad specificity for the phosphoryl acceptor substrate. Structural analogs of aspartic acid with a derivatized alpha-carboxyl group are accepted as alternative substrates by
