Association by 2,3-dihydroxybenzaldehyde of monomeric phenolase in spinach chloroplasts: Association by 2,3-dihydroxybenzaldehyde of monomeric phenolase in spinach chloroplasts. Sato, Mitsuhiko (Fac.Some chemicals with cas registry numbers like 9002-10-2 and 24677-78-9 are also used. Sci., Tokyo Metrop. Univ., Tokyo, Japan). Phytochemistry, 15(11), 1665-7 (English) 1976. CODEN: PYTCAS. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Section cross-reference(s): 7 In the presence of 5 mM 2,3-dihydroxybenzaldehyde, the monomeric phenolase (mol. wt. 36,000) of spinach chloroplasts was completely converted to its dimer within 6 h without significant change in activity. The aldehyde at concns. >0.25 mM could bring about this conversion after 18 h treatment. The assocn. of the 2 monomers becomes tighter with increasing concn. of the aldehyde. The dimer gave rise to a higher mol. wt. protein after freezing briefly. Several mono- and dihydroxybenzaldehydes, 2,3-dihydroxybenzoic acid, and o-vanillin did not produce the dimer. .

The obsd. frequencies have been assigned to various normal modes of vibration in light of the normal coordinate calcn.There are some commonly used reagents with their cas registry numbers 24677-78-9 and 139-85-5 in this article. using Wilson's classical FG-matrix method. All the 42 normal modes have been assigned for all the mols. for the first time. .
