Major-Histocompatibility-Complex Proteins Present Peptide Antigens on Cell Surfaces for Recognition by T-Cell Receptors

---

p. 984

Some of the internal proteins are broken into peptides, which are then bound to a complex of integral membrane proteins encoded by the major histocompatible complex (MHC).

A comparison with the calculated values of 5733.9 and 18,388 reveals that MALDI-TOF is clearly an accurate means of determining protein mass.

---

p. 86

Consider an example of a MALDI ion source coupled to a TOF mass analyser: the MALDI-TOF mass spectrometer (Figure 3.27).

---

p. 86

In Figure 3.28, the MALDI-TOF mass spectrum of a mixture of 5 pmol each of insulin and lactoglobulin is shown.

p. 667

Second, malate is oxidatively decarboxylated by an NADP⁺-linked malate enzyme (also called malic enzyme).

---

p. 663

The elongation phase of fatty acid synthesis starts with the formation of acetyl ACP and malonyl ACP. Acetyl transacylase and malonyl transacylase catalyze these reactions.

---

p. 664

An elongation cycle begins when malonyl/acetyl transacylase (MAT) moves an acetyl unit from coenzyme A to the acyl carrier protein (ACP).

A key feature of this detection system is the inclusion of a mammalian liver homogenate.

P680+, a very strong oxidant, extracts electrons from water molecules bound at the water-oxidizing complex (WOC), also called the manganese center.

---

p. 334

Under normal circumstances, the mannose 6-phosphate receptor, a lectin, binds the enzymes in the Golgi apparatus and directs them to the lysosome.

---

p. 85

However, the development of techniques such as matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization (ESI) has enabled the clearing of this significant hurdle.

---

p. 670

The mammalian multifunctional fatty acid synthase is a member of a large family of complex enzymes termed megasynthases that participate in step-by-step synthetic pathways.

At the cellular level, memory arises because positively selected B cells and T cells that have a high affinity for their target persist within the organism as memory B cells and memory T cells.

Another class of proteins that do not adhere to the paradigm is metamorphic proteins.

---

p. 996

MHC proteins embedded in the plasma membrane tenaciously grip their bound peptides so that they can be touched and scrutinized by T-cell receptors on the surface of a killer cell.

FIGURE 28.7 Minor-groove interactions. DNA polymerases donate two hydrogen bonds to base pairs in the minor groove. Hydrogen-bond acceptors are present in these two positions for all Watson-Crick base pairs, including the A-T base pair shown.

---

p. 830

First, residues of the enzyme form hydrogen bonds with the minor-groove side of the base pair in the active site (Figure 28.7).

Mitochondrial biogenesis is stimulated by muscular activity

---

p. 557

Because the maternally inherited mitochondria are present in large numbers and not all of the mitochondria may be affected, the pathologies of mitochondrial mutants con be quite complex.

---

p. 557-558

Although the details have not yet been established, the outer membrane of damaged mitochondria becomes highly permeable, a process referred to as mitochondrial outer membrane permeabilization (MOMP).

---

p. 242

Figure 8.34A shows an enzyme that displays molecular heterogeneity, with three active forms that catalyze the same reaction but at different rates.

---

p. 406

These molecular-imaging agents are greatly enhancing our understanding of signal-transduction processes.

---

p. 159

Foreign genes have been efficiently introduced into mammalian cells by infecting them with vectors derived from the Moloney murine leukemia virus, a retrovirus which can accept inserts as long as 6 kb.
