Some Major Steps in the Understanding of the Chemistry and Biochemistry of Chl - Chlorophyll Biosynthesis and Technological Applications - page 12

1.2.19 Smith and Kupke, 1956
In 1956, they extended their studies of Pchl-holochrome (Smith and Kupke 1956 ).
1.2.20 Goldberg, 1956
In 1956, Goldberg et al., described the insertion of ferrous iron into Proto by
ferrochelatase (Goldberg et al. 1956 ).
1.2.21 Shibata, 1957
In 1957, Shibata described an opal glass technique for the determination of the
spectral properties of intact leaves, and described a Chl-apoprotein spectral shift,
the Shibata shift, during greening of etiolated tissues (Shibata 1957 ).
1.2.22 Wolff and Price, 1957
In 1957, Wolff and Price demonstrated that the immediate product of Pchlide
a photoconversion is chlorophyllide (Chlide) a , which is then esterified to Chl a
in the dark. They proposed that the main route of Chl formation proceeds from
Pchlide to Chl a via Chlide a (Wolff and Price 1957 ).
1.2.23 Bogorad, 1958
In 1958, demonstrated the conversion of PBG to hexahydro Uro i.e. uroporphyrinogen
III (Urogen III) in a wheat germ extract (Bogorad 1958 ).
1.2.24 Mauzerall and Granick, 1958
In 1958, demonstrated the conversion of Urogen III to coproporphyrinogen III
(Coprogen III) in duck erythrocytes (Mauzerall and Granick 1958 ).
