MT-ATP8 (or ATP8) is a mitochondrial gene with the full name 'mitochondrially encoded ATP synthase membrane subunit 8' that encodes a subunit of mitochondrial ATP synthase, ATP synthase F o subunit 8 (or subunit A6L). This subunit belongs to the F o complex of the large, transmembrane F-type ATP synthase. [5]
Sav1866 is a homodimer of half transporters, and each subunit contains an N-terminal TMD with six helices and a C-terminal NBD. The NBDs are similar in structure to those of other ABC transporters, in which the two ATP binding sites are formed at the dimer interface between the Walker A motif of one NBD and the LSGGQ motif of the other.
Structure of a flippase, showing the two major subunits of the enzyme. Flippases are transmembrane lipid transporter proteins located in the cell membrane.They are responsible for aiding the movement of phospholipid molecules between the two layers, or leaflets, that compose the membrane (transverse diffusion, also known as a "flip-flop" transition).
A fully assembled Clp protease complex has a barrel-shaped structure in which two stacked ring of proteolytic subunits (ClpP or ClpQ) are either sandwiched between two rings or single-caped by one ring of ATPase-active chaperon subunits (ClpA, ClpC, ClpE, ClpX or ClpY). ClpXP is presented in almost all bacteria while ClpA is found in the Gram ...
The human MT-ATP6 gene, located in mitochondrial DNA, is 681 base pairs in length. [7] An unusual feature of MT-ATP6 is the 46-nucleotide gene overlap of its first codons with the end of the MT-ATP8 gene. With respect to the MT-ATP6 reading frame (+3), the MT-ATP8 gene ends in the +1 reading frame with a TAG stop codon.
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The number of peripheral stalks is dependent on the type of ATPase: F-ATPases have one, A-ATPases have two, and V-ATPases have three. The F 1 catalytic domain is located on the N-side (negative-side) of the membrane and is involved in the synthesis and degradation of ATP and is involved in oxidative phosphorylation.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
