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 form when two tectonic plates move together (a convergent plate boundary). Fold mountains form from sedimentary rocks that accumulate along the margins of continents.When plates and the continents riding on them collide, the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak layer such as salt.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.
