The Rossmann fold is a protein structural motif found in proteins that bind nucleotides, such as enzyme cofactors FAD, NAD, and NADP.The structure is composed of up to seven mostly parallel beta strands.The first two strands are connected by an Î±- helix. The structures of segments between additional strands vary greatly and may include structures such as short helical segments and coils.n 1989, Israel Hanukoglu from the Weizmann Institute of Science discovered that the consensus sequence for NADP binding site in some enzymes that utilize NADP differs from the NAD binding motif. This discovery was used to re-engineer coenzyme specificities of enzymes.
Fold mountains are mountains that form mainly by the effects of folding on layers within the upper part of the Earth's crust. Before either plate tectonic theory developed, or the internal architecture of thrust belts became well understood, the term was used for most mountain belts, such as the Himalayas.he forces responsible for formation of fold mountains are called orogenic movements. The term orogenic has derived from a Greek word meaning mountain building. These forces act at tangent to the surface of the earth and are primarily a result of plate tectonics.
