Figure 4.20 Detailed view of the zinc environment in carboxy-peptidase. The active-site zinc atom is bound to His 69 and Glu 72, which are part of the loop region outside P strand 2. In addition, His 196, which is the last residue of P strand 5, also binds the zinc. Figure 4.20 Detailed view of the zinc environment in carboxy-peptidase.

The presence of zinc at the catalytic site of liver alcohol dehydrogenase suggests comparison with other zinc-dependent enzymes [164], and three are shown in Fig. 37. The hand and geometry of the zinc environment is invariant with respect to the proton abstractor (L4 and Fig. 37), the zinc atom, substrate site, water position, and protein ligand cluster. Ligand LI is in each case histidine, and the planes of the... [Pg.152]

A full report on the structural determinations of the complexes [Zn(H2L)(H20)2]-CI2 and Zh2L2 [H2L = 2,6-diacetylpyridinebis-(2 -pyridylhydrazone)] mentioned in last year s report has appeared. Reaction of Zn(S03CF3)2 with the macrocycle (6 H2L) in the presence of a tertiary amine such as triethyl- or tri-n-propylamine, yields the complexes [ZnL(amine)] n.m.r. studies indicate the co-ordination geometry to be square-pyramidal with the amine in the apical position. The complex [ZnL],H20 of the quinquedentate Schiff base (7 H2L) has been prepared the zinc environment is a distorted trigonal bipyramid (Zn—O = 1.95 A Zn—N = 2.11 — 2.16A). ... [Pg.404]
