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 mountain. Fold mountains are mountains formed mainly by the effects of folding on layers in the upper part of the Earth's crust. The term is rather out of date, though still fairly common in physical geography literature. In the time before plate tectonics became well understood, the term was used for mountain belts, such as the Himalayas. These mountain ranges are not caused by the folding of the earth's crust. The main mechanism causing a thickening of the crust at these sites of continent-continent collision along a convergent boundary is thrust faulting. Fold mountains are formed when two tectonic plates move together (a convergent plate boundary).
